Genesis 18:6-8

And Abraham hastened into the tent unto Sarah, and said, Make ready quickly three measures of fine meal, knead it, and make cakes. And Abraham ran unto the herd, and fetched a calf tender and good, and gave it unto the servant; and he hasted to dress it. And he took butter, and milk, and the calf which he had dressed, and set it before them; and he stood by them under the tree, and they did eat.
