Genesis 18:6-8

The ‘quantity’ that Abraham said was ‘3 seahs’. That was a large quantity. And Abraham chose a young cow. He did not choose a young goat, which would be smaller. So this meal was a large one. Abraham was very generous to his guests. And he served his guests but he did not eat with them.

v9 The men said to Abraham, ‘Where is Sarah your wife?’ And he said, ‘She is in the tent.’ v10 The *Lord said, ‘I will certainly return to you in the spring. When I return, Sarah your wife shall have a son.’ And Sarah was behind him. She listened at the door of the tent.

v11 Now Abraham and Sarah were both very old. Women produce children until a certain age, but Sarah had passed that age. v12 So Sarah laughed to herself. She said to herself, ‘I have grown old and my husband is old. I cannot have a child. I cannot have that pleasure.’ v13 The *Lord said to Abraham, ‘Sarah should not have laughed. She should not have said, “I cannot have a child, since I am old.” v14 Nothing is too difficult for the *Lord. At the time that I have mentioned, I will return. In the spring, I will return to you. When I return, Sarah shall have a son.’ v15 And Sarah was afraid. Therefore she said, ‘I did not laugh.’ But the *Lord said, ‘No, you did laugh.’
