Deuteronomy 21:9
Swete's Septuagint · Berean Standard Bible
σὺ δὲ ἐξαρεῖς τὸ αἷμα τὸ ἀναίτιον ἐξ ὑμῶν αὐτῶν, ἐὰν ποιήσῃς τὸ καλὸν καὶ τὸ ἀρεστὸν ἔναντι κυρίου τοῦ θεοῦ σου.
So you shall purge from among you the guilt of shedding innocent blood, since you have done what is right in the eyes of the LORD.
