Genesis 18:9-19

‘Where is your wife Sarah?’ they asked him. ‘There, in the tent,’ he said. Then one of them said, ‘I will surely return to you about this time next year, and Sarah your wife will have a son.’ Now Sarah was listening at the entrance to the tent, which was behind him. Abraham and Sarah were already very old, and Sarah was past the age of childbearing. So Sarah laughed to herself as she thought, ‘After I am worn out and my lord is old, will I now have this pleasure?’ Then the LORD said to Abraham, ‘Why did Sarah laugh and say, “Will I really have a child, now that I am old?” Is anything too hard for the LORD? I will return to you at the appointed time next year, and Sarah will have a son.’ Sarah was afraid, so she lied and said, ‘I did not laugh.’ But he said, ‘Yes, you did laugh.’ When the men got up to leave, they looked down towards Sodom, and Abraham walked along with them to see them on their way. Then the LORD said, ‘Shall I hide from Abraham what I am about to do? Abraham will surely become a great and powerful nation, and all nations on earth will be blessed through him. For I have chosen him, so that he will direct his children and his household after him to keep the way of the LORD by doing what is right and just, so that the LORD will bring about for Abraham what he has promised him.’
