6 So Abraham ran back to the tent and said to Sarah, "Hurry! Get three large measures of your best flour, knead it into dough, and bake some bread." 7 Then Abraham ran out to the herd and chose a tender calf and gave it to his servant, who quickly prepared it. 8 When the food was ready, Abraham took some yogurt and milk and the roasted meat, and he served it to the men. As they ate, Abraham waited on them in the shade of the trees.

Commentary on Genesis 18:1-8
(Read Genesis 18:1-8)
Abraham was waiting to entertain any weary traveller, for inns were not to be met with as among us. While Abraham was thus sitting, he saw three men coming. These were three heavenly beings in human bodies. Some think they were all created angels; others, that one of them was the Son of God, the Angel of the covenant. Washing the feet is customary in those hot climates, where only sandals are worn. We should not be forgetful to entertain strangers, for thereby some have entertained angels unawares, Revelation 3:20.
