2 and he lifteth up his eyes and looketh, and lo, three men standing by him, and he seeth, and runneth to meet them from the opening of the tent, and boweth himself towards the earth, 3 And he saith, 'My Lord, if, I pray thee, I have found grace in thine eyes, do not, I pray thee, pass on from thy servant; 4 let, I pray thee, a little water be accepted, and wash your feet, and recline under the tree; 5 and I bring a piece of bread, and support ye your heart; afterwards pass on, for therefore have ye passed over unto your servant;' and they say, 'So mayest thou do as thou has spoken.' 6 And Abraham hasteth towards the tent, unto Sarah, and saith, 'Hasten three measures of flour-meal, knead, and make cakes;'

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.
