Isaiah 6:7
Rahlfs Septuagint (1935) · Berean Standard Bible
καὶ ἥψατο τοῦ στόματός μου καὶ εἶπεν ἰδοὺ ἥψατο τοῦτο τῶν χειλέων σου καὶ ἀφελεῖ τὰς ἀνομίας σου καὶ τὰς ἁμαρτίας σου περικαθαριεῖ
And with it he touched my mouth and said: “Now that this has touched your lips, your iniquity is removed and your sin is atoned for.”
