LXX Gen 48:4

καὶ εἰπέν μοι Ἴδου ἐγώ σε αὐξάνω καὶ πληθυνῶ καὶ ποιήσω σε εἰς συναγωγὰς ἐθνῶν, καὶ δώσω σοι τὴν γῆν ταύτην καὶ τῶ σπέρματί σου μετὰ σὲ εἰς κατάσχεσιν αἰώνιον.

and told me, ‘Behold, I will make you fruitful and multiply you; I will make you a multitude of peoples, and will give this land to your descendants after you as an everlasting possession.’
