“How much power in any case can mortals have? Let mortals hold on to justice; power will be given them when they are immortal. Compared with this, the power of those people who are called powerful on earth is shown to be ridiculous weakness, and "a pit is dug for the sinner" in the very place where the wicked seem to be able to do most. The just person sings, "Happy is the one whom you instruct, Lord, and teach from your law, in order to comfort him in evil days, until a pit is dug for the sinners. For the Lord will not reject his people or forsake his inheritance, until justice turns into judgment, and those who have it are all of an upright heart." So in this time during which the power of the people of God is being deferred, God will not reject his people or forsake his inheritance, however bitter and humiliating the trials it suffers in its humility and weakness, until the justice that now belongs to the weakness of the godly turns into judgment, that is until it receives the authority to judge, which is being reserved for the just in the end, when power follows in its proper order on the justice that preceded it.”

“"Until righteousness," he saith, "turn again unto judgment, and all they that have it are right in heart" (ver. 15). Listen now, and gain righteousness: for judgment thou canst not yet have. Thou shouldest gain righteousness first; but that very righteousness of thine shall turn unto judgment. The Apostles had righteousness here on earth, and bore with the wicked. But what is said unto them? "Ye shall sit on twelve thrones, judging the twelve tribes of Israel." Their righteousness therefore shall turn unto judgment. For whoever is righteous in this life, is so for this reason, that he may endure evils with patience: let him suffer patiently the period of suffering, and the day of judging cometh. But why do I speak of the servants of God? The Lord Himself, who is the Judge of all living and dead, first chose to be judged, and then to judge. Those who have righteousness at present, are not yet judges. For the first thing is to have righteousness, and afterwards to judge: He first endureth the wicked, and afterwards judgeth them. Let there be righteousness now: afterwards it shall turn again unto judgment. And so long He endureth wicked men, as God doth will, as long as God's Church shall endure them, that she may be taught through their wickedness. Nevertheless, God will not cast off His people, "all such as have it are right in heart." Who are those who are right in heart? Those whose will is the will of God. He spareth sinners: thou dost wish Him at once to destroy sinners. Thy heart is crooked and thy will perverted, when thy will is one way and the will of God another. God wisheth to spare sinners: thou dost not wish sinners spared. God is of long-suffering to sinners: thou dost not wish to endure sinners. ...Wish not to bend the will of God to thy will, but rather correct thy will to His. The will of God is like a rule: behold, suppose, thou hast twisted the rule: whence canst thou be set straight? But the rule itself continueth straight: for it is immutable. As long as the rule is straight, thou hast whither to turn thyself, and straighten thy perversity; thou hast a means of correcting what is crooked in thee. But what do men will? It is not enough that their own will is crooked; they even wish to make the will of God crooked according to their own heart, that God may do what they themselves will, when they ought to do that which God willeth. ...”

“For until righteousness will judgment return [i.e., the judgment of] their chastisements [will persist] until they become righteous because of them. And after the judgment, all those upright in heart will gather, for they will receive their reward.”

“But judgment shall return unto righteousness,.... Which may be understood either of the judgment and righteousness of God, which seemed to be parted, and stand at a distance from each other; his conduct and government of the world from his justice; the righteous being persecuted and afflicted, and wicked men suffered to prosper; which sometimes makes it difficult to reconcile the judgment of God, or his government of the world, to his justice; see Jer 12:1, but as this has been made manifest in the destruction of the Jews, and in the downfall of Rome Pagan, the first persecutors of the Christians; so it will be seen in Rome Papal, when the judgments of God will be manifest, and appear to be just and true; and these two, judgment and justice, will openly come together, in the sight of all; as they also will at the last judgment; see Rev 15:4 or else of the righteousness of men, which, in times of general corruption, seems to be fled from them, and to stand at a distance, from their conduct and behaviour; as in the old world before the flood, and in the times Isaiah beautifully describes, Isa 59:14, and in the times of Christ and his apostles; and in the persecuting times of Rome Pagan and Papal; and as it will be at the time of the slaying of the witnesses; but upon the rising of them, which will not be long after, there will be a great pouring down of the Spirit, and a general reformation will follow throughout the world; all the Lord's people will be righteous, not only nominally, but really; every pot in Jerusalem shall be holy; and holiness shall be so common as that it is said it shall be upon the bells of the horses; and in the new heavens and new earth will dwell none but righteous persons; and then judgment and righteousness will come together indeed: and all the upright in heart shall follow it; either judgment, as Jarchi; or righteousness, as Kimchi; not the righteousness of the law, but the righteousness of faith; or rather practical righteousness, works of righteousness, which both the grace wrought in them, and the doctrine of grace received by them, will teach, influence, and engage to pursue after with eagerness: or else the meaning is, that such who are "upright in heart"; who have new hearts and right spirits formed in them; who have the truth of grace, and the root of the matter, in them; whose hearts, words, and actions, agree; who are sincere souls, Israelites indeed, in whom is no guile; these will approve and applaud the righteous judgments of God upon antichrist; they shall follow the justice of God with their commendations and praises; see Rev 15:3. The words may be rendered, "and all the upright in heart shall be after him" (d), the Lord; they shall follow him whithersoever he goes, as sheep follow the shepherd, servants their masters, and soldiers their general; they shall follow him in his own ways, observe his commands, and obey his orders; see the description of such that will be with Christ, and follow him, before and at the time of antichrist's ruin, Rev 14:4. The Targum is, "after him shall be redeemed all the upright in heart.'' (d) "post ipsum", Musculus, Gejerus.”

“Until justice be turned into judgment, &c. By being put in execution: which will be agreeable to all the upright in heart. (Challoner) — They will be round the tribunal, and sit as judges with Christ. Hebrew ci had, “For to,” may have been originally ad ci, “Until.” (Haydock) — This does not imply that the just will not be protected afterwards. Cyrus was a figure of the Messias, and all his counsellors, or the Jews, attached themselves to him, when he punished the Babylonians, Isaias xli. 2., and liii. 11. (Calmet) — The Church will never be rejected by a just God, whose judgments must take place, and be pleasing to the righteous. (Worthington)”
