Genesis 18:10

Abraham ran to the herd, and fetched a tender and good calf, and gave it to the servant. He hurried to dress it.

He took butter, milk, and the calf which he had dressed, and set it before them. He stood by them under the tree, and they ate.

They asked him, “Where is Sarah, your wife?”

He said, “There, in the tent.”

Now Abraham and Sarah were old, well advanced in age. Sarah had passed the age of childbearing.

Sarah laughed within herself, saying, “After I have grown old will I have pleasure, my lord being old also?”

The LORD said to Abraham, “Why did Sarah laugh, saying, ‘Will I really bear a child when I am old?’
