LXX Gen 39:1

ἸωσὴΦ δὲ κατήχθη εἰς Αἴγυπτον· καὶ ἐκτήσατο αὐτὸν ΠετεΦρῆς ὁ εὐνοῦχος Φαραὼ ὁ ἀρχιμάγειρος, ἀνὴρ Αἰγύπτιος, ἐκ χειρῶν Ἰσμαηλει τῶν,οἳ κατήγαγον αὐτὸν ἐκεῖ.

Meanwhile, Joseph had been taken down to Egypt, where an Egyptian named Potiphar, an officer of Pharaoh and captain of the guard, bought him from the Ishmaelites who had taken him there.
