Matthew 5:39

Thou shalt not avenge, nor bear any grudge against the children of thy people, but thou shalt love thy neighbor as thyself: I am the LORD.

Behold, this day thine eyes have seen how that the LORD had delivered thee to day into mine hand in the cave: and some bade me kill thee: but mine eye spared thee; and I said, I will not put forth mine hand against my lord; for he is the LORD's anointed. Moreover, my father, see, yea, see the skirt of thy robe in my hand: for in that I cut off the skirt of thy robe, and killed thee not, know thou and see that there is neither evil nor transgression in mine hand, and I have not sinned against thee; yet thou huntest my soul to take it. The LORD judge between me and thee, and the LORD avenge me of thee: but mine hand shall not be upon thee. As saith the proverb of the ancients, Wickedness proceedeth from the wicked: but mine hand shall not be upon thee. After whom is the king of Israel come out? after whom dost thou pursue? after a dead dog, after a flea. The LORD therefore be judge, and judge between me and thee, and see, and plead my cause, and deliver me out of thine hand.

That this shall be no grief unto thee, nor offense of heart unto my lord, either that thou hast shed blood causeless, or that my lord hath avenged himself: but when the LORD shall have dealt well with my lord, then remember thine handmaid. And David said to Abigail, Blessed be the LORD God of Israel, which sent thee this day to meet me: And blessed be thy advice, and blessed be thou, which hast kept me this day from coming to shed blood, and from avenging myself with mine own hand. For in very deed, as the LORD God of Israel liveth, which hath kept me back from hurting thee, except thou hadst hasted and come to meet me, surely there had not been left unto Nabal by the morning light any that pisseth against the wall.

Then said Abishai to David, God hath delivered thine enemy into thine hand this day: now therefore let me smite him, I pray thee, with the spear even to the earth at once, and I will not smite him the second time. And David said to Abishai, Destroy him not: for who can stretch forth his hand against the LORD's anointed, and be guiltless? David said furthermore, As the LORD liveth, the LORD shall smite him; or his day shall come to die; or he shall descend into battle, and perish.

If I rejoice at the destruction of him that hated me, or lifted up myself when evil found him: Neither have I suffered my mouth to sin by wishing a curse to his soul. If the men of my tabernacle said not, Oh that we had of his flesh! we cannot be satisfied.

Say not thou, I will recompense evil; but wait on the LORD, and he shall save thee.
