Genesis 17:2

And I will make of thee a great nation, and I will bless thee, and make thy name great; and thou shalt be a blessing:

And I will make thy seed as the dust of the earth: so that if a man can number the dust of the earth, then shall thy seed also be numbered.

In the same day the LORD made a covenant with Abram, saying, Unto thy seed have I given this land, from the river of Egypt unto the great river, the river Euphrates:

That in blessing I will bless thee, and in multiplying I will multiply thy seed as the stars of the heaven, and as the sand which is upon the sea shore; and thy seed shall possess the gate of his enemies;

And I, behold, I establish my covenant with you, and with your seed after you;
