ἀνταποδίδωμι

For we know him that hath said, Vengeance belongeth unto me, I will recompense, saith the Lord. And again, The Lord shall judge his people.

For what thanks can we render to God again for you, for all the joy wherewith we joy for your sakes before our God;

Seeing it is a righteous thing with God to recompense tribulation to them that trouble you;

And thou shalt be blessed; for they cannot recompense thee: for thou shalt be recompensed at the resurrection of the just.

Or who hath first given to him, and it shall be recompensed unto him again?

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