Exodus 32:13; Genesis 15:5

13 Remember Abraham, Isaac, and Israel, your servants, to whom you pswore by your own self, and said to them, qI will multiply your offspring as the stars of heaven, and all this land that I have promised I will give to your offspring, and they shall inherit it forever.

And he brought him outside and said, Look toward heaven, and gnumber the stars, if you are able to number them. Then he said to him, hSo shall your offspring be.
