Genesis 18:6-8

Abraham hurried to the tent where Sarah was and said to her, “Hurry, prepare twenty quarts of fine flour, and make it into loaves of bread.” Then Abraham ran to his herd and took one of his best calves. He gave it to a servant, who hurried to kill it and to prepare it for food. Abraham gave the three men the calf that had been cooked and milk curds and milk. While they ate, he stood under the tree near them.
