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, Heb 13:2; nay, the Lord of angels himself; as we always do, when for his sake we entertain the least of his brethren. Cheerful and obliging manners in showing kindness, are great ornaments to piety. Though our condescending Lord vouchsafes not personal visits to us, yet still by his Spirit he stands at the door and knocks; when we are inclined to open, he deigns to enter; and by his gracious consolations he provides a rich feast, of which we partake with him, Re 3:20.
3. My Lord, if now I have found favor—The hospitalities offered are just of the kind that are necessary and most grateful, the refreshment of water, for feet exposed to dust and heat by the sandals, being still the first observed among the pastoral people of Hebron.
