Genesis 18:6-8
18:6 So Abraham hurried into the tent and said to Sarah, “Quick! Take three measures of fine flour, knead it, and make bread.”
18:7 Then Abraham ran to the herd and chose a fine, tender calf, and gave it to a servant, who quickly prepared it.
18:8 Abraham then took some curds and milk, along with the calf that had been prepared, and placed the food before them. They ate while he was standing near them under a tree.
