LXX Gen 22:17

εἰ μὴν μὴν εὐλογῶν εὐλογήσω σε, καὶ πλῆ πληθυνῶ τὸ σπέρμα σου ὡς τοὺς ἀστέρας τοῦ οὐρανοῦ καὶ ὡς τὴν τὴν παρὰ τὸ χεῖλος τῆς θαλάσσης· καὶ κληρονομήσει τὸ σπέρμα σου τὰς πόλεις τῶν ὑπεναντίων.

I will surely bless you, and I will multiply your descendants like the stars in the sky and the sand on the seashore. Your descendants will possess the gates of their enemies.
