וְאַתָּ֣ה אָמַ֔רְתָּ הֵיטֵ֥ב אֵיטִ֖יב עִמָּ֑ךְ וְשַׂמְתִּ֤י אֶֽת־זַרְעֲךָ֙ כְּח֣וֹל הַיָּ֔ם אֲשֶׁ֥ר לֹא־יִסָּפֵ֖ר מֵרֹֽב׃
And Thou saidst: I will surely do thee good, and make thy seed as the sand of the sea, which cannot be numbered for multitude.’
Targum Jonathan on Genesis
But Thou hast promised, I will surely do thee good, and will make thy sons many as the sand of the sea be numbered for that cannot be numbered for multitude.
