'Love Your Enemies' in the Bible

In that you love your enemies, and hate your friends. For you have declared this day, that you regard neither princes nor servants: for this day I perceive, that if Absalom had lived, and all we had died this day, then it would have pleased you well.

But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them who despitefully use you, and persecute you;

But I say unto you who hear, Love your enemies, do good to them who hate you,

But love your enemies, and do good, and lend, hoping for nothing in return; and your reward shall be great, and you shall be the children of the Highest: for he is kind unto the unthankful and to the evil.
