Parallel
Deuteronomy 32:41
Swete's Septuagint · Berean Standard Bible
ὅτι παροξυνῶ ὡς ἀστραπὴν τὴν μάχαιράν μου, καὶ ἀνθέξεται κρίματος ἡ χείρ μου, καὶ ἀποδώσω δίκην τοῖς ἐχθοῖς, καὶ τοῖς μισοῦσιν ἀνταποδώσω·
when I sharpen My flashing sword, and My hand grasps it in judgment, I will take vengeance on My adversaries and repay those who hate Me.
