7 Then he ran to the herd and selected a choice, tender calf and gave it to a servant, who hurried to prepare it.

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.
