Genesis 21:1-4 Amplified Bible (AMP)

1. THE Lord visited Sarah as He had said, and the Lord did for her as He had promised.

2. For Sarah became pregnant and bore Abraham a son in his old age, at the set time God had told him.

3. Abraham named his son whom Sarah bore to him Isaac [laughter].

4. And Abraham circumcised his son Isaac when he was eight days old, as God had commanded him.
