Three visitors

Not long afterward, during the heat of the day, Abraham had been sitting at the entrance of his tent by the terebinths of Mamre. He looked up and saw three men in the presence of God. Then he ran and bowed to the ground to welcome them. Abraham then offered to wash their feet and fetch them a morsel of bread, to which they assented. Abraham rushed to Sarah's tent to order ash cakes made from choice flour, then he ordered a servant-boy to prepare a choice calf. When all was prepared, he set curds, milk and the calf before them, waiting on them, under a tree, as they ate.

One of the visitors told Abraham that upon his return next year, Sarah would have a son. While at the tent entrance, Sarah overheard what was said and she laughed to herself about the prospect of having a child at their ages. The visitor inquired of Abraham why Sarah laughed at bearing a child at her age, as nothing is too hard for God. Frightened, Sarah denied laughing.
