Gen 17:23 ¶ Then Abraham took Ishmael his son, and all the servants who were born in his house and all who were bought with his money, every male among the men of Abraham's household, and circumcised the flesh of their foreskin in the very same day, as God had said to him.

Gen 18:1 Now the LORD appeared to him by the oaks of Mamre, while he was sitting at the tent door in the heat of the day.

Gen 18:3 and said, "My Lord, if now I have found favor in Your sight, please do not pass Your servant by.

Gen 18:6 So Abraham hurried into the tent to Sarah, and said, "Quickly, prepare three measures of fine flour, knead it and make bread cakes."

Gen 18:13 And the LORD said to Abraham, "Why did Sarah laugh, saying, 'Shall I indeed bear a child, when I am so old?'
