Genesis 18:6-8

6So Abraham hurried into the tent to Sarah. “Quick,” he said, “get three seahs of the finest flour and knead it and bake some bread.” 7Then he ran to the herd and selected a choice, tender calf and gave it to a servant, who hurried to prepare it. 8He then brought some curds and milk and the calf that had been prepared, and set these before them. While they ate, he stood near them under a tree.
