The 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 fullness of time, the Son of God was to make to the world, when the Word would be flesh, and appear as one of us. Observe here,

I.How Abraham expected strangers, and how richly his expectations were answered (Gen 18:1): He sat in the tent-door, in the heat of the day; not so much to repose or divert himself as to seek an opportunity of doing good, by giving entertainment to strangers and travellers, there being perhaps no inns to accommodate them. Note, 1. We are likely to have the most comfort of those good works to which we are most free and forward. 2. God graciously visits those in whom he has first raised the expectation of him, and manifests himself to those that wait for him. When Abraham was thus sitting, he saw three men coming towards him. These three men were three spiritual heavenly beings, now assuming human bodies, that they might be visible to Abraham, and conversable with him. Some think that they were all created angels, others that one of them was the Son of God, the angel of the covenant, whom Abraham distinguished from the rest (Gen 18:3), and who is called Jehovah, Gen 18:13. The apostle improves this for the encouragement of hospitality, Heb 13:2. Those that have been forward to entertain strangers have entertained angels, to their unspeakable honour and satisfaction. Where, upon a prudent and impartial judgment, we see no cause to suspect ill, charity teaches us to hope well and to show kindness accordingly. It is better to feed five drones, or wasps, than to starve one bee.

II.How Abraham entertained those strangers, and how kindly his entertainment was accepted. The Holy Ghost takes particular notice of the very free and affectionate welcome Abraham gave to the strangers. 1. He was very complaisant and respectful to them. Forgetting his age and gravity, he ran to meet them in the most obliging manner, and with all due courtesy bowed himself towards the ground, though as yet he knew nothing of them but that they appeared graceful respectable men. Note, Religion does not destroy, but improve, good manners, and teaches us to honour all men. Decent civility is a great ornament to piety. 2. He was very earnest and importunate for their stay, and took it as a great favour, Gen 18:3, Gen 18:4. Note, (1.) It becomes those whom God has blessed with plenty to be liberal and open-hearted in their entertainments, according to their ability, and (not in compliment, but cordially) to bid their friends welcome. We should take a pleasure in showing kindness to any; for both God and man love a cheerful giver. Who would eat the bread of him that has an evil eye? Pro 23:6, Pro 23:7. (2.) Those that would have communion with God must earnestly desire it and pray for it. God is a guest worth entertaining. 3. His entertainment, though it was very free, was yet plain and homely, and there was nothing in it of the gaiety and niceness of our times. His dining-room was an arbour under a tree; no rich table-linen, no side-board set with plate. His feast was a joint or two of veal, and some cakes baked on the hearth, and both hastily dressed up. Here were no dainties, no varieties, no forced-meats, no sweet-meats, but good, plain, wholesome food, though Abraham was very rich and his guests were very honourable. Note, We ought not to be curious in our diet. Let us be thankful for food convenient, though it be homely and common; and not be desirous of dainties, for they are deceitful meat to those that love them and set their hearts upon them. 4. He and his wife were both of them very attentive and busy, in accommodating their guests with the best they had. Sarah herself is cook and baker; Abraham runs to fetch the calf, brings out the milk and butter, and thinks it not below him to wait at table, that he might show how heartily welcome his guests were. Note, (1.) Those that have real merit need not take state upon them, nor are their prudent condescensions any disparagement to them. (2.) Hearty friendship will stoop to any thing but sin. Christ himself has taught us to wash one another's feet, in humble love. Those that thus abase themselves shall be exalted. Here Abraham's faith showed itself in good works; and so must ours, else it is dead, Jam 2:21, Jam 2:26. The father of the faithful was famous for charity, and generosity, and good house-keeping; and we must learn of him to do good and to communicate. Job did not eat his morsel alone, Job 31:17.

I will fetch a morsel of bread - This was the third requisite, and is introduced in its proper order; as eating immediately after exertion or fatigue is very unwholesome. The strong action of the lungs and heart should have time to diminish before any food is received into the stomach, as otherwise concoction is prevented, and fever in a less or greater degree produced.

For therefore are ye come - In those ancient days every traveler conceived he had a right to refreshment, when he needed it, at the first tent he met with on his journey.

So do as thou hast said - How exceedingly simple was all this! On neither side is there any compliment but such as a generous heart and sound sense dictate.

And I will fetch a morsel of bread,.... A piece or a loaf of bread, as De Dieu shows the word signifies; bread being put for all the necessaries of life:

and comfort ye your hearts; eat to refresh your spirits and renew your strength, that ye may be able to pursue your journey: and

after that ye shall pass on your way; I will retard you no longer:

for therefore are ye come to your servant; not that he thought they came this way on purpose to take some refreshment with him, but so it was ordered by the providence of God; and since it was, he desires that they would accept of his invitation:

and they said, so do as thou hast said; they agreed to it, that water should be fetched to wash their feet, and food for them to eat.

for therefore are ye come--No questions were asked. But Abraham knew their object by the course they took--approaching directly in front of the chief sheik's tent, which is always distinguishable from the rest and thus showing their wish to be his guests.
