Genesis 18:6-8

6So Abraham hurried into the tent to Sarah and said, “Quick! Knead three measures of fine flour and prepare bread loaves!”

7Then to the herd Abraham ran and took a young ox, tender and good, and he gave it to the servant, who prepared it quickly.

8Then he took butter and milk and the young ox that he had prepared and set it before them. While he was standing by them under the tree, they ate.
