Luke
Luke 6:35ESV·traditional attribution

But love your enemies, and do good, and lend, expecting nothing in return, and your reward will be great, and you will be sons of the Most High, for he is kind to the ungrateful and the evil.

John Calvin Reformed @genevareformer

Luke 6:35. Lend, expecting nothing again. It is a mistake to confine this statement to usury, as if Christ only forbade his people to be usurers. The preceding part of the discourse shows clearly, that it has a wider reference.

Matthew Henry Presbyterian @wholebiblehenry

These verses agree with Mat 5:38, to the end of that chapter: I say unto you that hear (Luk 6:27), to all you that hear, and not to disciples only, for these are lessons of universal concern. He that has an ear, let him hear. Those that diligently hearken to Christ shall find he has something to say to them well worth their hearing.

Be ye therefore merciful,.... Tenderhearted, kind, beneficent to all men, friends and foes: as your Father also is merciful; that is your Father which is in heaven; who is good to all, and his tender mercies are over all his works: nothing is more common in Zohar (y), and the Talmud (z) than to express the Divine Being by no other name, than "the Merciful"...
