Genesis 18:6, 9-10

So Abraham ran back to the tent and said to Sarah, “Hurry! Get three large measures of your best flour, knead it into dough, and bake some bread.”

“Where is Sarah, your wife?” the visitors asked. “She’s inside the tent,” Abraham replied. Then one of them said, “I will return to you about this time next year, and your wife, Sarah, will have a son!” Sarah was listening to this conversation from the tent.
