LXX Gen 16:2

εἶπεν δὲ Σάρα πρὸς Ἀβράμ ἰδοὺ συνέκλεισέν με Κύριος τοῦ μὴ τίκτειν· εἴσελθε οὖν πρὸς τὴν παιδίσκην μου, ἴνα τεκνοποιήσεις ἐξ αὐτῆς. ὑπήκουσεν δὲ Ἀβρὰμ τῆς φωνῆς αὐτῆς.

So Sarai said to Abram, “Look now, the LORD has prevented me from bearing children. Please go to my maidservant; perhaps I can build a family by her.” And Abram listened to the voice of Sarai.
