Genesis 18:6-8

6So Abraham hurried into the tent to Sarah and said, “Quickly, make ready three measures of fine meal; knead it and make cakes.”

7And Abraham ran to the herd, took a tender and good calf, gave it to a young man, and he hastened to prepare it.

8So he took butter and milk and the calf which he had prepared, and set it before them; and he stood by them under the tree as they ate.
