Thou shalt not avenge, nor bear any grudge against the children of thy people, but thou shalt love thy neighbour as thyself: I am the LORD. (Leviticus 19:18)

Rejoice not when thine enemy falleth, and let not thine heart be glad when he stumbleth: (Proverbs 24:17)

Ye have heard that it hath been said, An eye for an eye, and a tooth for a tooth: But I say unto you, That ye resist not evil: but whosoever shall smite thee on thy right cheek, turn to him the other also. And if any man will sue thee at the law, and take away thy coat, let him have thy cloke also. And whosoever shall compel thee to go a mile, go with him twain. (Matthew 5:38-41)

But love ye your enemies, and do good, and lend, hoping for nothing again; and your reward shall be great, and ye shall be the children of the Highest: for he is kind unto the unthankful and to the evil. (Luke 6:35)

Dearly beloved, avenge not yourselves, but rather give place unto wrath: for it is written, Vengeance is mine; I will repay, saith the Lord. (Romans 12:19)

Who, when he was reviled, reviled not again; when he suffered, he threatened not; but committed himself to him that judgeth righteously: (1 Peter 2:23)
