When Abram was ninety-nine years old, the LORD appeared to him and said, "I am God Almighty; serve me faithfully and live a blameless life.
I will make a covenant with you, by which I will guarantee to make you into a mighty nation."
At this, Abram fell face down in the dust. Then God said to him,
"This is my covenant with you: I will make you the father of not just one nation, but a multitude of nations!
What's more, I am changing your name. It will no longer be Abram; now you will be known as Abraham, for you will be the father of many nations.
