Isaiah 65:16 Douay-Rheims

In which he that is blessed upon the earth, shall be blessed in God, amen: and he that sweareth in the earth, shall swear by God, amen: because the former distresses are forgotten, and because they are hid from my eyes.

“For whoever blesses himself on the earth For My fear shall be over all of them, and the earth shall be full of knowledge, and whoever praises himself or lauds himself on the earth, will bless himself by the true God, he will praise himself that he is a servant of the true God, the God of truth, Who realized and observed this, His promise. for the first troubles have been forgotten Therefore, they shall call Me the true God.”

המתברך He who blesseth himself. This word is not like ונברכו and shall be blessed (Gen. 18:18); there is a difference between the two words. באלהי אמן In the God whom all the world will acknowledge to be the true God, and that there is none besides Him. אמן is an adjective of the same root as אמונה truth (25:1); יתברך ונו׳ Shall bless himself, etc. He shall thankfully acknowledge that this is true, or wish and pray that it may become true. Because the former troubles, etc., are hid from mine eyes. The troubles which have befallen the righteous, the servants of the Lord, have been intensified by the circumstance that the wicked used to mock at the pious and their piety, when the latter were afflicted with calamities”

“They have sought. Here the judge, namely God, gives the sentence concerning the distinguishing of the evil from the good, in the receiving of the promised salvation. And it is divided into two parts. In the first he pronounces the sentence of distinction; in the second he determines the manner of its execution, chapter 66: Thus says the Lord. Concerning the first, two things. First he promises a response, showing the fitting occasion for responding: They have sought; as if he were to say: until now you Jews were not seeking from me, but from idols. Since you now seek, I will respond. Mystically, concerning the conversion of the Gentiles. Romans 10: I was found by those who did not seek. And he sets down the promise: I said: Behold, I am to a nation: I will respond, namely, to the Jews, or I will turn to the nations that have been converted. Song of Songs 6: I am my beloved's, and my beloved is mine. Second, he pronounces the sentence of distinction: I have spread out my hands; and first he pronounces the distinguishing of the evil from the good on account of the sins of transgression; second, on account of the sins of omission: And you who have forsaken. The first is divided into two. In the first he threatens the wicked with punishments; in the second he promises the good their rewards: Thus says the Lord. Concerning the first, two things. First he charges them with the fault of transgression; second he threatens the punishment: These shall be smoke. He charges them with their fault on three grounds. First, from ingratitude for his benefits: I have spread out — by giving many benefits — all the day, that is, the whole time since I took them to myself. Mystically, on the cross. Jeremiah 16: Each one walks. Second, from the continuity of their sinning: a people before the face, because all things are naked and open to his eyes. Hebrews 4. Or because they set up an idol in the temple. Deuteronomy 32: They have provoked me with that which is not God. Third, from the diversity or gravity of their sins, with respect to four things. First, with respect to the worship of idols: who sacrifice — to idols — in gardens, because they worshipped idols in pleasurable places; upon bricks — upon altars built out of bricks, so that they could sustain the fire of the sacrifice. Above, chapter 1: They shall be confounded by their idols. Second, with respect to their pursuit of divinations: who dwell among the tombs, so that they might have answers from the dead; and in shrines — temples of idols, so called from diluendo, washing away, because there they thought all things were washed clean. Or because of the fountains that were there for washing the victims. And the priests sleep — upon the skins of the victims, for the sake of divination. Ezekiel 6: Your shrines shall be broken down. Third, with respect to the uncleanness of foods: who eat; and a profane broth, of swine. Below, the last chapter: those who ate swine's flesh, and the abomination, and the mouse, shall be consumed together. Fourth, with respect to their contempt of the just, who say — namely, to those not adoring idols; Wisdom 2: He is grievous to us; or who say — to God, Job 21: who say to God: Depart from us, we do not desire the knowledge of your ways. These shall be smoke. Here he threatens the punishment: and first the length of the punishment: smoke; that is, as smoke is consumed by fire; and they shall be kindled in my wrath. Deuteronomy 32: A fire is kindled in my fury, and shall burn even to the depths of hell. Second, the certainty of the punishment: Behold, it is written; because the sin is fixed firmly in memory, and the punishment in predetermination. I will not keep silence, dissembling. Jeremiah 17: The sin of Judah is written; above, chapter 42: I have kept silence, I have always held my peace. Third, the multitude of the punishments, because for all the sins of the fathers: but I will repay. Exodus 20: I am a jealous God, visiting the sins of the fathers upon the children. They have reproached — by adoring idols upon the high places; and for the sins also of their youth: and I will measure back — as if to say, I will measure the punishment to match the fault. Above, chapter 40: She has received double from the hand of the Lord. Thus says the Lord. Here he promises the good their rewards: and first, with respect to their preservation from evils: the grain, of the grape, a blessing; that is, it pleases God that it be kept in reserve as a blessing, for the sake of the servants: our fathers, that is, the whole race of the Jews. Above, chapter 17: It shall be like one gathering. Second, with respect to their advancement in goods: and first with respect to the multiplying of seed: And I will bring forth from Jacob. Above, chapter 1: Unless the Lord of hosts had left us a seed, we should have been like Sodom. Second, with respect to the restoring of their ancestral inheritance: And they shall inherit. Ezekiel 36: They shall possess you as an inheritance, and you shall be their inheritance. Third, with respect to the abundance of pastures: and there shall be plains, and the valley of Achor — named from him who was stoned there, Joshua 7. Hosea 2: I will give them the valley of Achor, to open hope. And you who have forsaken. Here he distinguishes the wicked from the consolation of the good, on account of their sins of omission: and first he threatens the wicked with punishments; second, the good with rewards, because to oblivion. Concerning the first, two things. First he threatens them because they have forsaken God, setting down the fault: and you, O Jews, to Fortune — the god of the Egyptians — a table: he touches upon the rite by which it was worshipped, because at the end of the year a table was prepared for it, laden with every kind of food. Deuteronomy 32: They forsook God who made them, and departed from God their savior. Setting down also the punishment: I will number; as if to say: so that none shall remain who is not oppressed. Jeremiah 44: They shall fall by the sword and by famine. Second, because they did not obey him calling them back, setting down the fault: because I called. Proverbs 1: I called, and you refused; and he threatens the punishment of this distinction, first in the satiety of the body: therefore thus says the Lord, Psalm 33: The rich have wanted and suffered hunger, but they that seek the Lord shall not be deprived of any good. Second, in the gladness of heart: Behold, my servants shall rejoice. Wisdom 5: Doing penance. Third, in the difference of name. And first he sets down what the name of the impious shall be: and you shall leave — as an oath, so that they might confirm their words thus: if it is not so, may it happen to me just as to them. Jeremiah 44: They shall die by the sword and by famine; and they shall be for an oath, and for a wonder, and for a curse, and for a reproach. And then he sets down what the name of the good shall be: and his servants — in which name, namely, the name is Jesus — Amen, that is, faithfully. Above, chapter 62: You shall be called by a new name, which the mouth of the Lord has named. Because to oblivion. Here he promises the seen rewards. And first, in general, with respect to the removal of evils: because to oblivion — not from a defect of knowledge, but from the succession of goods. Above, chapter 54: You shall forget the confusion of your youth. And with respect to the restoring of goods: for behold, I create new heavens — new helps from heaven; a new earth — new benefits from the earth. Or with reference to the day of judgment, when the world shall be renewed unto the glory of the saints. Apocalypse 21: The former things have passed away. Second, in particular: for behold, I create Jerusalem. And first, with respect to the gladness of hearts: Jerusalem — the earthly one; but rather heavenly exultation, emphatically, so that it might be wholly absorbed in joy. Above, chapter 35: They shall obtain joy and gladness, and sorrow and mourning shall flee from them. Second, with respect to the length of life: there shall no longer be one who does not fulfill — dying before his time; but the child shall die at a hundred years old, that is, when he has come to such an age; and if there be a sinner, although he has lived so long, he shall be subject to a curse. Genesis 25: Abraham died in a good old age. Mystically, in the heavenly Jerusalem all shall fulfill their days, because no one shall die. The child of a hundred years, that is, he who has lived childishly even up to the age of old age, shall die, with an eternal death. Wisdom 4: For venerable old age is not that of long time, nor counted by the number of years. Third, with respect to the prosperity of goods: both with respect to the security of possessions, and they shall build. Psalm: And they built houses; Amos, the last chapter: They shall plant vineyards. And he assigns the reason: for according to the days, that is, because they shall live long, just as the wood of a tree lasts long. They shall grow old; that is, they shall remain for their use even unto old age. Psalm 1: He shall be like a tree which is planted near the running waters. Above, chapter 49: They have labored in vain. And also with respect to the peace of their children: neither shall they beget in trouble, as those begetting children into the servitude of enemies. Ecclesiasticus 44: Good things continue with their seed. Fourth, with respect to the hearing of prayers: and it shall be, before they cry — with the mouth. Above, chapter 30: At the voice of your cry, as soon as he shall hear, he will answer you. Fifth, with respect to the tranquility of peace: the wolf and the lamb; because those who were formerly tyrants and evildoers shall dwell peaceably with others; above, chapter 11, the same.”

“That he who blesseth himself in the earth,.... That is sensible he stands in need of blessings, and wishes for them, and prays he might have them; or that takes notice that he is blessed with them, and acknowledges them, and is thankful for them: shall bless himself in the God of truth; shall pray to him for blessings he wants, and ascribe what he has unto him, and give him the praise and glory of them; by whom is meant, either God the Father, in opposition to idols, the fictitious deities of the Gentiles, those lying vanities, which were not gods by nature, and to whom the God of truth, or the true God, is often opposed, and whom the Targum here calls the living God; or rather the Messiah, our Lord Jesus Christ: for the words may be rendered, "shall bless himself in God Amen" (f); that is, in God, who is the "Amen", which is one of the names of Christ, Rev 3:14 in whom believers are blessed with all spiritual blessings, and reckon themselves blessed in him, and ascribe blessing to him for them; in whom all the promises of God are yea and amen, and who is the true God, and eternal life, Co2 1:20, and he that sweareth in the earth shall swear by the God of truth; when an oath is necessary on any account, and it is proper to appeal to the supreme Being for the truth of anything, this, in Gospel times, should be done in the name of Christ; he, who is the Amen and faithful witness, is to be appealed unto, who is God omniscient, the discerner of the thoughts and intents of the heart. Of forms of swearing by Christ, see Rom 9:1. Besides, swearing, as it is a part of religious worship, may here be put for the whole; so it signifies, that as all blessings come from Christ, so all worship and duty should be performed unto him, and in his name. Because the former troubles are forgotten, they are hid from mine eyes; which is to be understood not of afflictions and persecutions for the sake of Christ and his Gospel, for these, especially in the first times of it, were very great; though in the latter day they will cease, to which indeed this prophecy extends: but rather either of the idolatry and superstition of the Gentile world, which were troublesome and offensive to God, but now removed by the clear light of the Gospel, and so forgotten by him, and hid from his eyes; or the carnal ordinances of the legal dispensation, which gave great trouble to the worshippers then, and could not cleanse their consciences, and through the fear of death, on the breach of them, were all their lifetime subject to bondage; but now these are all done away by Christ, and in Gospel times forgotten by men, and hid from the sight of God, who regards them no more; see Jer 3:16, which sense suits with what follows. (f) "benedicet sibi in Deo Amen", Pagninus, Montanus, Vitringa; "benedicturus sit in Deo Amen", Cocceius.”

“Amen, or “of truth.” False gods shall be neglected. They shall not swear by them, as formerly, Sophonias i. 5. — Christ usually adopted the asseveration, Amen, Amen, to enforce his truths. (Haydock)”

“That he--rather, "he who," &c. blesseth, &c.-- (Psa 72:17; Jer 4:2). God of truth--very God, as opposed to false gods; Hebrew, Amen: the very name of Messiah (Co2 1:20; Rev 3:14), faithful to His promises (Joh 1:17; Joh 6:32). Real, substantial, spiritual, eternal, as opposed to the shadowy types of the law. sweareth, &c.--God alone shall be appealed to as God (Isa 19:18; Deu 6:13; Psa 63:11). troubles--that is, sins, provocations [LOWTH]. Rather, calamities caused by your sins; so far from these visiting you again, the very remembrance of them is "hid from Mine eyes" by the magnitude of the blessings I will confer on you (Isa 65:17, &c.).
