Genesis 21:8 WBT

⁶  And Sarah said, God hath made me to laugh, [so that] all that hear will laugh with me.

⁷  And she said, Who would have said to Abraham, that Sarah shall nurse children? for I have borne him a son in his old age.

⁸  And the child grew, and was weaned: and Abraham made a great feast the day that Isaac was weaned.

⁹  And Sarah saw the son of Hagar the Egyptian, which she had borne to Abraham, mocking.

¹⁰  Wherefore, she said to Abraham, Cast out this bond-woman, and her son: for the son of this bond-woman shall not be heir with my son, [even] with Isaac.
