Genesis 15:3

And Abram said, [I am grieved] since thou hast given me no seed, but my home-born [servant] shall succeed me.

And Abram said, Behold, to me thou hast given no seed: and, lo, one born in my house is mine heir.

Abram said, “Behold, you have given no children to me: and, behold, one born in my house is my heir.”
