1Pet 3:9

“"Wherefore, girding up your loins," "serve the Lord in fear" and truth, as those who have forsaken the vain, empty talk and error of the multitude, and "believed in Him who raised up our Lord Jesus Christ from the dead, and gave Him glory," and a throne at His right hand. To Him all things in heaven and on earth are subject. Him every spirit serves. He comes as the Judge of the living and the dead. His blood will God require of those who do not believe in Him. But He who raised Him up from the dead will raise up us also, if we do His will, and walk in His commandments, and love what He loved, keeping ourselves from all unrighteousness, covetousness, love of money, evil speaking, false witness; "not rendering evil for evil, or railing for railing," or blow for blow, or cursing for cursing, but being mindful of what the Lord said in His teaching: "Judge not, that ye be not judged; forgive, and it shall be forgiven unto you; be merciful, that ye may obtain mercy; with what measure ye mete, it shall be measured to you again;" and once more, "Blessed are the poor, and those that are persecuted for righteousness' sake, for theirs is the kingdom of God."”

“How much more, while you are returning the malediction in the name of Jupiter himself, are you doing honour to Jupiter in the same way as he who provoked you! But a believer ought to laugh in such cases, not to rave; nay, according to the precept, not to return a curse in the name of God even, but dearly to bless in the name of God, that you may both demolish idols and preach God, and fulfil discipline.”

“Not rendering evil for evil,.... Doing an ill thing in return to one that has done ill to you, and in a way of revenge for it; which is contrary to what is before advised to, and which is taking God's prerogative and work out of his hands, whose vengeance is, and which is to be overcome of evil: or railing for railing; returning ill language to such as have given it, but rather should imitate Christ, who, when he was reviled, reviled not again, Pe1 2:23 and whose advice is, instead of returning injuries, blows, or words, to turn to him that smites on the right check the other also and to bless them that curse, do good to them that hate, and pray for them that persecute, Mat 5:39 and which is here directed to: but contrariwise blessing; praying for a blessing on them; for if we are to do so for our enemies, for them that hate us, despitefully use and persecute us, as did Christ, Stephen the protomartyr, and the apostles, then much more our fellow Christians who may do us an injury or speak evil of us, or to us: who seem to be chiefly intended: the argument to persuade to it follows, knowing that ye are thereunto called; referring either to what goes before being called by grace to the discharge of all the above duties exhorted to, and particularly to suffer patiently all injuries and affronts; and instead of making returns in the same way, to bless and pray for those that have hurt us, either by words or deeds; see Pe1 2:20 or to what follows, that ye should inherit a blessing; temporal blessing or blessings; for godliness has the promise of this life and godly persons shall not want any good thing; and even while the blessings of others are cursed they have their outward mercies with a blessing, and they are blessings indeed to them; wherefore, the little they may have is better than the large affluence of others: and also spiritual blessing, or blessings; such as peace of conscience, the pardon of all their sins a justifying righteousness adopting grace, all supplies of grace from Christ, his presence and communion with him: and also an eternal one, even life for evermore; called so, because it springs from the free favour, good will, and blessing of God, and which its being an inheritance also shows; and because such that enjoy it are eternally and unspeakably happy.”

“Not rendering evil for evil - Purposing, saying, doing nothing but good; and invariably returning good for evil. Ye are thereunto called - This is your calling - your business in life, to do good, and to do good for evil, and to implore God's blessing even on your worst enemies. And this is not only your duty, but your interest; for in so doing you shall obtain God's blessing, even life for evermore.”

“evil--in deed. railing--in word. blessing--your revilers; participle, not a noun after "rendering." knowing that--The oldest manuscripts read merely, "because." are--Greek, "were called." inherit a blessing--not only passive, but also active; receiving spiritual blessing from God by faith, and in your turn blessing others from love [GERHARD in ALFORD]. "It is not in order to inherit a blessing that we must bless, but because our portion is blessing." No railing can injure you (Pe1 3:13). Imitate God who "blesses" you. The first fruits of His blessing for eternity are enjoyed by the righteous even now (Pe1 3:10) [BENGEL].”
