Genesis 21:1-6 MSG

1 God visited Sarah exactly as he said he would; God did to Sarah what he promised:
2 Sarah became pregnant and gave Abraham a son in his old age, and at the very time God had set.
3 Abraham named him Isaac.
4 When his son was eight days old, Abraham circumcised him just as God had commanded.
5 Abraham was a hundred years old when his son Isaac was born.
6 Sarah said, God has blessed me with laughter and all who get the news will laugh with me!
