Exodus 4:15
Swete's Septuagint · Berean Standard Bible
καὶ ἐρεῖς πρὸς αὐτὸν καὶ δώσεις τὰ ῥήματά μου εἰς τὸ στόμα αὐτοῦ· καὶ ἐγὼ ἀνοίξω τὸ στόμα σου καὶ τὸ στόμα αὐτοῦ, καὶ συμβιβάσω ὑμᾶς ἃ ποιήσετε.
You are to speak to him and put the words in his mouth. I will help both of you to speak, and I will teach you what to do.
