Isaiah 50:1 Douay-Rheims

Thus saith the Lord: What is this bill of the divorce of your mother, with which I have put her away? or who is my creditor, to whom I sold you: behold you are sold for your iniquities, and for your wicked deeds have I put your mother away.

“"Did my hand reap the crop? And did it drop?" that is, Is it tired and weakened? He is inspired by what happens to the harvesters, from whose hands the ears escape. For he teaches, through these words, that it is from them that the cause of their afflictions derives and not from him.”

ספר כריתות Bill of divorcement. Of your mother and her husband.—This verse seems to contradict the prophecy of Jeremiah, I had put her away and given her a bill of divorce (3:8); but in fact the latter refers to the kingdom of the ten tribes which will never again be established; comp. She shall no more rise (Am. 5:2); but Isaiah speaks of the kingdom of the house of David, which will be restored by Messiah.”

“Thus says the Lord: Who is this, etc. Here he begins to remove the impediments to liberation: and first he removes the impediments; second he applies remedies, chapter 53: Who has believed the report, etc. Concerning the first he removes three impediments. First, the lack of divine benefits; second, the rejection of persons, chapter 51: Hear me, you who follow, etc.; third, the poverty of things, chapter 52: Arise, arise, etc. Concerning the first, three things. First he excludes the impediment; second he sets himself forth as an example: The Lord has given me, etc.; third he concludes with wholesome counsel: Who among you that fears, etc. Concerning the first, two things. First he excludes the lack of divine benefits on the part of the divine will, second on the part of the divine power: Is it shortened, etc. Concerning the first, three things. First he excludes a defect of the divine will, as though God of himself did not wish to do good, excluding a twofold manner of alienation: namely, the manner of putting away a wife, which was by a bill of divorce, as is said in Deuteronomy 24, which indeed was permitted to them on account of the hardness of their heart, Matthew 19: Who is this, etc. But against this, Jeremiah 3: because she had committed adultery, etc. And it must be said that the Lord, as far as is in himself, did not repudiate them; but they, through their own sins, forsook God. He also excludes the manner of alienating a possession: Or who is the creditor, etc., as if to say: you who are my inheritance. Above, 19: I should have sold to him, not having anything else to pay — whence it is clear that, since I have not alienated you from my lordship, I am prepared to do good as far as it is in me. Second, he shows the sin of the human will: For behold, in iniquities — Romans 7: For I am a carnal man, sold under sin. Third, he sets forth an argument: because I came, through inspiration; I called, through the prophets. Proverbs 1: I called, and you refused. Is it shortened? Here he excludes the defect on the part of the divine power, excluding first a defect of power: shortened, as though I could not even subject those far off to myself; small, against powers. Below, 59: Behold, the hand of the Lord is not shortened. Second, he sets forth a sign of the divine power: Behold. First in the waters: in rebuke, that is, at command, I will do it, if I will, just as I did at the going out of Israel from Egypt, Exodus 14; I will make rivers, as the Arnon, Numbers 21, and the Jordan, Joshua 4; they will rot, as in Exodus 7, when the waters were turned into blood. Psalm 105: He rebuked the Red Sea, and it was dried up. Second, he shows signs of his power in the heavens: I will clothe the heavens — the airy ones — with darkness, as in Egypt, Exodus 10. Psalm 146: Who covers the heaven with clouds. The Lord has given. Here he sets himself forth as an example: and first as to the grace of the benefit received; then as to eloquence — a learned tongue, to sustain, with encouragements: Job 4: they strengthened the wavering; then also as to wisdom — he raises up, to attend, in the morning, from the beginning of my preaching, or from the beginning of my age. Or because at that time he was accustomed to pray, Psalm 62: In the mornings I will meditate on you. He has opened, for understanding, Psalm 84: I will hear what the Lord God speaks in me. Matthew 23: One is your master, Christ. Second, he sets himself forth as an example as to obedience, setting forth perfect obedience: But I do not contradict — rather I receive, and I accept his inspiration; I did not go backward, from a good purpose. Above, 45: Woe to him who contradicts his maker. He also sets forth the constancy of obeying, because he did not give up obedience for any danger: I have given my body; that is, I exposed myself to suffer such things. Or perhaps he suffered these things literally; but it was fully fulfilled in Christ, Matthew 26 and 27. Jeremiah 12: I have given my beloved soul into the hands of enemies. Third, he sets himself forth as an example as to the confidence which he had in God, first setting forth a ready defense: The Lord God is a helper — Jeremiah 20: The Lord is with me like a strong warrior. Second, the security of that confidence: and he set me, that I might not be moved by fear or shame. Ezekiel 3: I have made you like adamant and flint. Third, he assigns the reason for the security from the power of the one helping: Near is he who justifies, namely, God. Who will contradict? By words. Let us stand together. Job 17: Set me, Lord, next to you, and let anyone's hand fight against me. Adversary — by deeds. Let him condemn — by false judgments. Romans 8: God who justifies, who is it that condemns? Again, from the weakness of the one attacking: Behold, all of them like a garment — by old age, in which there is a natural defect; the moth, in which there is violence. Job 13: who am to be consumed like rottenness, and like a garment that is eaten by a moth. As if he were to say: from all these things, just as I, after having received benefits, obey God and trust in him, so also you. Who among you? Here he concludes, from his own example, a wholesome counsel: and first he sets forth the counsel; second he sets forth the contempt of the counsel: Behold, all of you. Now he gives counsel that they should trust in God: whence he does three things. First he requires the fitness of those who trust, which is from fear and obedience — servant, of Isaiah, or of whatever other. Psalm 24: Who is the man who fears the Lord? Second he shows the necessity of confidence: who has walked in darkness — of error, or of adversity. John 11: He who walks in the night stumbles. Third he sets forth the counsel itself: let him hope in the name; above, 10: the remnant of Israel, etc. Behold, all. Here he sets forth the contempt of the counsel, setting forth three things. First the fault: kindling — by your sins — a fire, meriting it for yourselves; girded — as though bound in your sins, or made ready for sin. Above, 1: your strength shall be as the ash of tow. Second he sets forth the punishment: walk — as if he were to say, receive the punishment. Psalm 9: The sinner is caught in the labors of his own hands. Third he sets forth the power of the one punishing: from the hand, namely, of the power of God. You shall sleep — the sleep of death. Note, on that word, you are sold in iniquities, that man sells many things for sin. First, the virtue of the soul: Lamentations 1: They gave up all their precious things for a vile price. Second, the heavenly inheritance: 3 Kings 21: The Lord be merciful to me, that I should not sell the inheritance of my fathers. Third, the liberty of the soul: Ecclesiasticus 10: Nothing is more wicked than to love money. Fourth, the honor of divine love: Hosea 3: the Lord loves. Also, on that word, But I do not contradict, note that men contradict God: first, the unfaithful contradict the divine truth. Ecclesiasticus 4: Do not contradict the word of truth. Second, the impatient contradict the divine correction. Job 9: who contradicts him? etc. Third, the impenitent contradict the divine goodness. Above, 41: and they shall be as if they were not. Fourth, the disobedient contradict the divine authority. Hosea 4: your people. Also, on that word, you shall sleep in sorrows, that sinners grieve in death. First, on account of the loss of bodily things: Job 27: When the rich man shall sleep, he shall carry nothing with him. Second, on account of the contradiction of conscience: Wisdom 5: doing penance, and groaning for anguish of spirit. Third, on account of despair of future glory: Lamentations, last chapter: The crown has fallen from our head. Woe to us, for we have sinned. Fourth, on account of fear of punishment: Psalm 47: There sorrows as of a woman in labor, etc.”

“Those who have professed to be the people of God, and yet seem to be dealt severely with, are apt to complain of God, and to lay the fault upon him, as if he had been hard with them. But, in answer to their murmurings, we have here, I. A challenge given them to prove, or produce any evidence, that the quarrel began on God's side, Isa 50:1. They could not say that he had done them any wrong or had acted arbitrarily. 1. He had been a husband to them; and husbands were then allowed a power to put away their wives upon any little disgust: if their wives found not favour in their eyes, they made nothing of giving them a bill of divorce, Deu 24:1; Mat 19:7. But they could not say that God had dealt so with them. It is true they were now separated from him, and had abode many days without ephod, altar, or sacrifice; but whose fault was that? They could not say that God had given their mother a bill of divorce; let them produce it if they can, for a bill of divorce was given into the hand of her that was divorced. 2. He had been a father to them; and fathers had then a power to sell their children for slaves to their creditors, in satisfaction for the debts they were not otherwise able to pay. Now it is true the Jews were sold to the Babylonians then, and afterwards to the Romans; but did God sell them for payment of his debts? No, he was not indebted to any of those to whom they were sold, or, if he had sold them, he did not increase his wealth by their price, Psa 44:12. When God chastens his children, it is neither for his pleasure (Heb 12:10) nor for his profit. All that are saved are saved by a prerogative of grace, but those that perish are cut off by an act of divine holiness and justice, not of absolute sovereignty. II. A charge exhibited against them, showing them that they were themselves the authors of their own ruin: "Behold, for your iniquities, for the pleasure of them and the gratification of your own base lusts, you have sold yourselves, for your iniquities you are sold; not as children are sold by their parents, to pay their debts, but as malefactors are sold by the judges, to punish them for their crimes. You sold yourselves to work wickedness, and therefore God justly sold you into the hands of your enemies, Ch2 12:5, Ch2 12:8. It is for your transgressions that your mother is put away, for her whoredoms and adulteries," which were always allowed to be a just cause of divorce. The Jews were sent into Babylon for their idolatry, a sin which broke the marriage covenant, and were at last rejected for crucifying the Lord of glory; these were the iniquities for which they were sold and put away. III. The confirmation of this challenge and this charge. 1. It is plain that it was owing to themselves that they were cast off; for God came and offered them his favour, offered them his helping hand, either to prevent their trouble or to deliver them out of it, but they slighted him and all the tenders of his grace. "Do you lay it upon me?" (says God); "tell me, then, wherefore, when I came, was there no man to meet me, when I called, was there none to answer me?" Isa 50:2. God came to them by his servants the prophets, demanding the fruits of his vineyard (Mat 21:34); he sent them his messengers, rising up betimes and sending them (Jer 35:15); he called to them to leave their sins, and so prevent their own ruin: but was there no man, or next to none, that had any regard to the warnings which the prophets gave them, none that answered the calls of God, or complied with the messages he sent them; and this was it for which they were sold and put away. Because they mocked the messengers of the Lord, therefore, God brought upon them the king of the Chaldeans, Ch2 36:16, Ch2 36:17. Last of all he sent unto them his Son. He came to his own, but his own received him not; he called them to himself, but there were none that answered; he would have gathered Jerusalem's children together, but they would not; they knew not, because they would not know, the things that belonged to their peace, nor the day of their visitation, and for that transgression it was that they were put away and their house was left desolate, Mat 21:41; Mat 23:37, Mat 23:38; Luk 19:41, Luk 19:42. When God calls men to happiness, and they will not answer, they are justly left to be miserable. 2. It is plain that it was not owing to a want of power in God, for he is almighty, and could have recovered them from so great a death; nor was it owing to a want of power in Christ, for he is able to save to the uttermost. The unbelieving Jews in Babylon thought they were not delivered because their God was not able to deliver them; and those in Christ's time were ready to ask, in scorn, Can this man save us? For himself he cannot save. "But" (says God) "is my hand shortened at all, or is it weakened?" Can any limits be set to Omnipotence? Cannot he redeem who is the great Redeemer? Has he no power to deliver whose all power is? To put to silence, and for ever to put to shame, their doubts concerning his power, he here gives unquestionable proofs of it. (1.) He can, when he pleases, dry up the seas, and make the rivers a wilderness. He did so for Israel when he redeemed them out of Egypt, and he can do so again for their redemption out of Babylon. It is done at his rebuke, as easily as with a word's speaking. He can so dry up the rivers as to leave the fish to die for want of water, and to putrefy. When God turned the waters of Egypt into blood he slew the fish, Psa 105:29. The expression our Saviour sometimes used concerning the power of faith, that it will remove mountains and plant sycamores in the sea, is not unlike this; if their faith could do that, no doubt their faith would save them, and therefore they were inexcusable if they perished in unbelief. (2.) He can, when he pleases, eclipse the lights of heaven, clothe then with blackness, and make sackcloth their covering (Isa 50:3) by thick and dark clouds interposing, which he balances, Job 36:32; Job 37:16.”

“Thus saith the Lord,.... Here begins a new discourse or prophecy, and therefore thus prefaced, and is continued in the following chapter: where is the bill of your mother's divorcement, whom I have put away? these words are directed to the Jews, who stood in the same relation to the Jewish church, or synagogue, as children to a mother; and so the Targum interprets "your mother" by "your congregation", or synagogue; who were rejected from being a church and people; had a "loammi" written upon them, which became very manifest when their city and temple were destroyed by the Romans; and this is signified by a divorce, alluding to the law of divorce among the Jews, Deu 24:1, when a man put away his wife, he gave her a bill of divorce, assigning the causes of his putting her away. Now, the Lord, either as denying that he had put away their mother, the Jewish church, she having departed from him herself, and therefore challenges them to produce any such bill; a bill of divorce being always put into the woman's hands, and so capable of being produced by her; or if there was such an one, see Jer 3:8, he requires it might be looked into, and seen whether the fault was his, or the cause in themselves, which latter would appear: or which of my creditors is it to whom I have sold you? referring to a practice used, that when men were in debt, and could not pay their debts, they sold their children for the payment of them; see Exo 21:7, but this could not be the case here; the Lord has no creditors, not any to whom he is indebted, nor could any advantage possibly accrue to him by the sale of them; it is true they were sold to the Romans, or delivered into their hands, which, though a loss to them, was no gain to him; nor was it he that sold them, but they themselves; he was not the cause of it, but their own sins, as follows: behold, for your iniquities have ye sold yourselves; or, "are sold" (w); they were sold for them, or delivered up into the hands of their enemies on account of them; they had sold themselves to work wickedness, and therefore it was but just that they should be sold, and become slaves: and for your transgressions is your mother put away; and they her children along with her, out of their own land, and from being the church and people of God.

“Away. Such a one could not be received again, if she had taken another husband, Deuteronomy xxiv. 3. Some explain this of the captives. But God restored them to favour. It seems rather to relate to the reprobation (Calmet) of the synagogue, which will never again become the true Church, (Haydock) though many of Israel will be converted, Romans xi. 25. — Sold you, as a father might do, Exodus xxi. 1., and Matthew xviii. 15. St. Ambrose (Tob.[Tobias?] viii.) inveighs against such cruel parents, as the Christian religion had not then entirely repressed this inhumanity.

“Th* selling of a debtor, for the satisfaction of claims against him, serves as an image of the voluntary bondage which the sinner contracts ; his offences placing him in the power of his enemy. " Your sins and crimes sold you to demons ; so that, being entangled in the pleasures of this world, you forsook your mother, as she forsook her Spouse." St. Jerome.”
