2. Easton's Bible Dictionary “Easton's Bible Dictionary: Justification — A forensic term, opposed to condemnation. As regards its nature, it is the judicial act of God, by which he pardons all the sins of those who believe in Christ, and accounts, accepts, and treats them as righteous in the eye of the law, i.e., as conformed to all its demands. In addition to the pardon (q.v.) of sin, justification declares that all the claims of the law are satisfied in respect of the justified. It is the act of a judge and not of a sovereign. The law is not relaxed or set aside, but is declared to be fulfilled in the strictest sense; an”

5. Numbers (Protestant academic) “Tyndale House on Numbers 35:15: 35:15-24 The Old Testament makes a clear distinction between deliberate murder and involuntary manslaughter (35:11, 22-23; Exod 21:12-14; cp. Num 15:22-31). Murder required a penalty of execution, but an accidental death did not. The cities of refuge provided protection only for those who killed another person by accident. • The use of a weapon was proof of malicious intent. 35:15 Israelites, foreigners living among you, and traveling merchants. Anyone: The same law applied impartially to everyone; Israel had one standard of justice, not two (one for citizens, a”
6. Romans (Baptist/Reformed) “John Gill on Romans 5:7: For scarcely for a righteous man will one die,.... The design of this, and the following verse, is to show that Christ's dying for ungodly persons is an instance of kindness that is matchless and unparalleled. By "a righteous man", is not meant a truly gracious, holy man; nor one that is made righteous by the obedience of Christ; but one that is so in his own eyes, and in the esteem of others, being outwardly moral and righteous before men; who keeps to the letter of the law, and does, as he imagines, what that externally requires: such were the Pharisees among the Jew”
7. Romans (Methodist/Wesleyan) “Adam Clarke on Romans 4:5: But to him that worketh not - Which was the case with Abraham, for he was called when he was ungodly, i.e. an idolater; and, on his believing, was freely justified: and, as all men have sinned, none can be justified by works; and, therefore, justification, if it take place at all, must take place in behalf of the ungodly, forasmuch as all mankind are such. Now, as Abraham's state and mode in which he was justified, are the plan and rule according to which God purposes to save men; and as his state was ungodly, and the mode of his justification was by faith in the goo”
8. Luke (Baptist/Reformed) “John Gill on Luke 23:37: And we indeed justly,.... For sins committed against the law; our sentence is just, we are righteously punished: which shows that he had a true sense of sin; for where that is, there will be not only an acknowledgment of the offence, but a vindication of the justice of God, should he proceed to deal according to the demerit of sin: for we receive the due reward of our deeds; though, according to the law of Moses, theft was not punishable with death, but with a restoration, either double, or fourfold, or fivefold, according to the nature of it; see Exo 22:1. It may be t”
9. Galatians (Methodist/Wesleyan) “Adam Clarke on Galatians 2:16: Knowing that a man is not justified - See the notes on Rom 1:17; Rom 3:24 (note), Rom 3:27 (note); Rom 8:3 (note). And see on Act 13:38 (note) and Act 13:39 (note), in which places the subject of this verse is largely discussed. Neither the works of the Jewish law, nor of any other law, could justify any man; and if justification or pardon could not have been attained in some other way, the world must have perished. Justification by faith, in the boundless mercy of God, is as reasonable as it is Scriptural and necessary.”
10. Romans (Baptist/Reformed) “John Gill on Romans 5:9: Much more then being now justified by his blood,.... The apostle here argues from justification by Christ to salvation by him, there being a certain and inseparable connection between these two; whoever is justified shall be saved; and speaks of justification "as being now by his blood". Justification in God's mind from eternity proceeded upon the suretyship engagements of Christ to be performed in time; the Old Testament saints were justified of God with a view to the blood of the Lamb which was to be shed; this blood was "now" shed, and an application of justificatio”
11. James (Baptist/Reformed) “John Gill on James 5:6: Ye have condemned and killed the just,.... Meaning not Christ, the Just One, as some have thought; whom the Jewish sanhedrim condemned as guilty of death, and got the sentence passed upon him, and him to be crucified by Pontius Pilate, on the day of slaughter, at the time of the passover, as some connect the last clause of the preceding verse with this; since the apostle is not writing to the Jerusalem Jews, nor to unbelievers, but to professors of religion; though he might say they did it, because their nation did it: but rather this is to be understood of the poor sai”
