Bible Verses About The First Born: Ishmael

And God said to Abraham: Sara thy wife shall bear thee a son, and thou shalt call his name Isaac, and I will establish my covenant with him for a perpetual covenant, and with his seed after him.

And as for Ismael I have also heard thee. Behold, I will bless him, and increase, and multiply him exceedingly: he shall beget twelve chiefs, and I will make him a great nation.

But my covenant I will establish with Isaac, whom Sara shall bring forth to thee at this time in the next year.
