Romans 12:20
Patriarchal Greek New Testament (1904) · Berean Standard Bible
ἐὰν οὖν πεινᾷ ὁ ἐχθρός σου, ψώμιζε αὐτόν, ἐὰν διψᾷ, πότιζε αὐτόν· τοῦτο γὰρ ποιῶν ἄνθρακας πυρὸς σωρεύσεις ἐπὶ τὴν κεφαλὴν αὐτοῦ.
On the contrary, “If your enemy is hungry, feed him; if he is thirsty, give him a drink. For in so doing, you will heap burning coals on his head (note: Proverbs 25:21–22 (see also LXX)).”
