Greek translation (Brenton) of Gen. 9:22-23

καὶ εἶδε Χὰμ ὁ πατὴρ Χαναὰν τὴν γύμνωσιν τοῦ πατρὸς αὐτοῦ καὶ ἐξελθὼν ἀνήγγειλε τοῖς δυσὶν ἀδελφοῖς αὐτοῦ ἔξω. καὶ λαβόντες Σὴμ καὶ ᾿Ιάφεθ τὸ ἱμάτιον ἐπέθεντο ἐπὶ τὰ δύο νῶτα αὐτῶν καὶ ἐπορεύθησαν ὀπισθοφανῶς καὶ συνεκάλυψαν τὴν γύμνωσιν τοῦ πατρὸς αὐτῶν, καὶ τὸ πρόσωπον αὐτῶν ὀπισθοφανῶς, καὶ τὴν γύμνωσιν τοῦ πατρὸς αὐτῶν οὐκ εἶδον.

And Ham the father of Canaan saw the nakedness of his father, and he went out and told his two brothers without. And Sem and Japheth having taken a garment, put it on both their backs and went backwards, and covered the nakedness of their father; and their face was backward, and they saw not the nakedness of their father.
