Isaac

Facts:

Isaac was the only son of Abraham and Sarah. God had promised to give them a son even though they were very old.

The name "Isaac" means "he laughs." When God told Abraham that Sarah would give birth to a son, Abraham laughed because they were both very old. Some time later, Sarah also laughed when she heard this news.
But God fulfilled his promise and Isaac was born to Abraham and Sarah in their old age.
God told Abraham that the covenant he had made with Abraham would also be for Isaac and his descendants forever.
When Isaac was a youth, God tested Abraham's faith by commanding him to sacrifice Isaac.
Isaac's son Jacob had twelve sons whose descendants later became the twelve tribes of the nation of Israel.
