And the child grew, and was weaned: and Abraham made a great feast the [same] day that Isaac was weaned.

And Sarah saw the son of Hagar the Egyptian, which she had born unto Abraham, mocking.

Wherefore she said unto Abraham, Cast out this bondwoman and her son: for the son of this bondwoman shall not be heir with my son, [even] with Isaac.
