The Lord visits Abraham and assures Sarah of the birth of a son. Abraham is sitting in the tent door in the heat of the day, reposing. "Three men stood before him." Whenever visitants from the celestial world appear to men, they have the form of man. This is the only form of a rational being known to us. It is not the design of God in revealing his mercy to us to make us acquainted with the whole of the nature of things. The science of things visible or invisible he leaves to our natural faculties to explore, as far as occasion allows. Hence, we conclude that the celestial visitant is a real being, and that the form is a real form. But we are not entitled to infer that the human is the only or the proper form of such beings, or that they have any ordinary or constant form open to sense. We only discern that they are intelligent beings like ourselves, and, in order to manifest themselves to us as such, put on that form of intelligent creatures with which we are familiar, and in which they can intelligibly confer with us. For the same reason they speak the language of the party addressed, though, for ought we know, spiritual beings use none of the many languages of humanity, and have quite a different mode of communicating with one another. Other human acts follow on the occasion. They accept the hospitality of Abraham and partake of human food. This, also, was a real act. It does not imply, however, that food is necessary to spiritual beings. The whole is a typical act representing communion between God and Abraham. The giving and receiving of a meal was the ground of a perpetual or inviolable friendship.

He ran to meet him. - This indicates the genuine warmth of unsophisticated nature. "Bowed himself to the earth." This indicates a low bow, in which the body becomes horizontal, and the head droops. This gesture is employed both in worship and doing obeisance.

And the Lord appeared - See note on Genesis 15:1.

Sat in the tent door - For the purpose of enjoying the refreshing air in the heat of the day, when the sun had most power. A custom still frequent among the Asiatics.

And the Lord appeared unto him in the plains of Mamre,.... That is, to Abraham; and very likely this appearance of God was quickly after the affair of the circumcision, to show his approbation of his ready obedience to his command; and at this time he was in the plains, or at the oaks of Mamre, the oaken grove there, as has been observed on Genesis 13:18; and which seems to be the best rendering of the words, since in Genesis 18:4; mention is made of a tree to sit and stand under; and Abraham might choose this place for his habitation, because of the shadiness of it, in those hot countries:

and he sat in the tent door, in the heat of the day; partly to cool and refresh himself, and partly to observe if any passengers passed by, to invite them in; this being a time of day when such needed refreshment, and it was proper for them to lie by a while, and not proceed on their journey until it was cooler: or rather to or "near" the tent door, as Noldius (g), or before it, without or under the shade of the tree, after mentioned.

(g) Ebr. Concord. Part. p. 13.

When sitting, about mid-day, in the grove of Mamre, in front of his tent, Abraham looked up and unexpectedly saw three men standing at some distance from him (עליו above him, looking down upon him as he sat), viz., Jehovah (Genesis 18:13) and two angels (Genesis 19:1); all three in human form. Perceiving at once that one of them was the Lord (אדני, i.e., God), he prostrated himself reverentially before them, and entreated them not to pass him by, but to suffer him to entertain them as his guests: "Let a little water be fetched, and wash your feet, and recline yourselves (השּׁען( sevle to recline, leaning upon the arm) under the tree." - "Comfort your hearts:" lit., "strengthen the heart," i.e., refresh yourselves by eating and drinking (Judges 19:5; 1 Kings 21:7). "For therefore (sc., to give me an opportunity to entertain you hospitably) have ye come over to your servant:" כּן על כּי does not stand for כּי כּן על (Ges. thes. p. 682), but means "because for this purpose" (vid., Ewald, 353).

And the LORD appeared unto him in the plains of Mamre: and he sat in the tent door in the heat of the day;

18:1 This appearance of God to Abraham seems to have had in it more of freedom and familiarity, and less of grandeur and majesty, than those we have hitherto read of, and therefore more resembles that great visit which in the fulness of time the Son of God was to make to the world. He sat in the tent - door in the heat of the day - Not so much to repose himself, as to seek an opportunity of doing good, by giving entertainment to strangers.

plains of Mamre-rather, terebinth or oak of Mamre; a tall-spreading tree or grove of trees.

sat in the tent door-The tent itself being too close and sultry at noon, the shaded open front is usually resorted to for the air that may be stirring.

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.
