LXX Gen 17:23

Καὶ ν Ἀβραὰμ Ἱσμαὴλ τὸν υἱὸν αὐτοῦ καὶ πάντας τοὺς οἰκογενεῖς αὐτοῦ καὶ πάντας τοὺς ἀργυρωνήτους καὶ Καὶ ἄρσεν τῶν ἀνδρῶν τῶν ἐν τῷ οἴκῳ Ἀβραάμ, καὶ περιέτεμεν τὰς ἀκροβυστίας αὐτῶν ἐν τῷ καιρῷ τῆς ἡμέρας ἐκείνης, καθὰ ἐλάλησεν αὐτῷ ὁ θεός.

On that very day Abraham took his son Ishmael and all those born in his household or purchased with his money—every male among the members of Abraham’s household—and he circumcised them, just as God had told him.
