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.

Verse 4. - Let a little water, I pray yon, be fetched, and wash your feet. Feet washing was a necessary part of Oriental hospitality (cf. Genesis 19:2; Genesis 24:32; Genesis 43:24). "Among the ancient Egyptians the basins kept in the houses of the rich for this purpose were sometimes of gold" (Freeman, Bible Manners, 'Homiletic Quarterly,' vol. 1. p. 78). "In India it is considered a necessary part of hospitality to wash the feet and ankles of the weary traveler, and even in Palestine this interesting custom is not extinct. Dr. Robinson and party on arriving at Ramleh repaired to the abode of a wealthy Arab, where the ceremony was performed in the genuine style of ancient Oriental hospitality (vide Kitto's 'Bible Illustrations,' vol. 1. p. 230). And rest yourselves (literally, recline by resting on the elbow) under the tree.

Let a little water, I pray you, be fetched, and wash your feet,.... Which was very refreshing to travellers in hot countries, who walked barefoot or in sandals; and this he proposes to be done by one of his servants, whose business it was, only desires they would give him leave to order it, 1 Samuel 25:41; and so it was usual in other countries, and in later times, for servants to fetch water to wash the hands and feet of guests (l):

and rest yourselves under the tree; before the tent door, under which doubtless were seats to sit down upon, where they might rest their weary limbs; it is very probable this was an oak tree, and which, and a turpentine tree the ancient writers speak of, continued unto the times of Constantine; see Gill on Genesis 13:18; and the Jewish writers say (m), that now near the city (Hebron), between the vineyards, are the oaks of Mamre, where is the house of Abraham our father, on whom be peace, and the tree under which the angels ate, and the stone on which he (Abraham) sat when he was circumcised.
