Romans 12:19

Dearly beloved
This affectionate appellation the apostle makes use of, expressing his great love to them, the rather to work upon then, and move them to an attention to what he is about to say; which they might assure themselves was in great tenderness to them, for their good, as well as the glory of God: moreover, he may hereby suggest to them, not only that they were dear to him, but that they were greatly beloved of God, that they were high in his favour and affection; and this he might him unto them, in order to melt them into love to their fellow Christians and fellow creatures, and even to their enemies, and never think of private revenge:

avenge not yourselves;
this is no ways contrary to that revenge, a believer has upon sin, and the actings of it, which follows on true evangelical repentance for it, ( 2 Corinthians 7:11 ) , and lies in a displicency at it, and himself for it, and in abstaining from it, and fighting against it; nor to that revenge a church may take of the disobedience of impenitent and incorrigible offenders, by laying censures on them, withdrawing from them, and rejecting them from their communion; nor to that revenge which civil magistrates may execute upon them that do evil; but this only forbids and condemns private revenge in private persons, for private injuries done, and affronts given:

but rather give place to wrath;
either to a man's own wrath, stirred up by the provocations given him; let him not rush upon revenge immediately; let him sit down and breathe upon it; let him "give" (arta) , "space", unto it, as the Syriac, which may signify time as well as place; and by taking time his wrath will, subside, he will cool and come to himself, and think better on it: or to the wrath of the injurious person, by declining him, as Jacob did Esau, till his wrath was over; or by patiently hearing without resistance the evil done, according to the advice of Christ, ( Matthew 5:39 Matthew 5:40 ) ; or to the wrath of God, leave all with him, and to the day of his wrath and righteous judgment, who will render to every man according to his works; commit yourselves to him that judgeth righteously, and never think of avenging your own wrongs; and this sense the following words incline to,

for it is written,
( Deuteronomy 32:35 ) ;

vengeance is mine, I will repay, saith the Lord;
vengeance belongs to God, and to him only; it is proper and peculiar to him, not to Heathen deities, one of which they call (dikh) , "vengeance"; see ( Acts 28:4 ) ; nor to Satan, who is of a revengeful spirit, and is styled the enemy and the avenger; nor to men, unless to magistrates under God, who are revengers and executioners of his wrath on wicked men; otherwise it solely belongs to God the lawgiver, whose law is broken, and against whom sin is committed: and there is reason to believe he will "repay" it, from the holiness of his nature, the strictness of his justice, his power and faithfulness, his conduct towards his own people, even to his Son, as their surety; nor will he neglect, but in his own time will avenge his elect, which cry unto him day and night; and who therefore should never once think of avenging themselves, but leave it with their God, to whom it belongs.
