These angels, it is likely, were two of the three that had just before been with Abraham, the two created angels that were sent to execute God's purpose concerning Sodom. Observe here, 1. There was but one good man in Sodom, and these heavenly messengers soon found him out. Wherever we are, we should enquire out those of the place that live in the fear of God, and should choose to associate ourselves with them. Mat 10:11, Enquire who is worthy, and there abide. Those of the same country, when they are in a foreign country, love to be together. 2. Lot sufficiently distinguished himself from the rest of his neighbours, at this time, which plainly set a mark upon him. He that did not act like the rest must not fare like the rest. (1.) Lot sat in the gate of Sodom at even. When the rest, it is likely, were tippling and drinking, he sat alone, waiting for an opportunity to do good. (2.) He was extremely respectful to men whose mien and aspect were sober and serious, though they did not come in state. He bowed himself to the ground, when he met them, as if, upon the first view, he discerned something divine in them. (3.) He was hospitable, and very free and generous in his invitations and entertainments. He courted these strangers to his house, and to the best accommodations he had, and gave them all the evidences that he could of his sincerity; for, [1.] When the angels, to try whether he was hearty in the invitation, declined the acceptance of it, at first (which is the common usage of modesty, and no reproach at all to truth and honesty), their refusal did not make him more importunate; for he pressed upon them greatly (Gen 19:3), partly because he would be no means have them to expose themselves to the inconveniences and perils of lodging in the street of Sodom, and partly because he was desirous of their company and converse. He had not seen two such honest faces in Sodom this great while. Note, Those that live in bad places should know how to value the society of those that are wise and good, and earnestly desire it. [2.] When the angels accepted his invitation, he treated them nobly; he made a feast for them, and thought it well-bestowed on such guests. Note, Good people should be (with prudence) generous people.

Two angels - The two referred to Gen 18:22.
Sat in the gate - Probably, in order to prevent unwary travelers from being entrapped by his wicked townsmen, he waited at the gate of the city to bring the strangers he might meet with to his own house, as well as to transact his own business. Or, as the gate was the place of judgment, he might have been sitting there as magistrate to hear and determine disputes.
Bowed himself - Not through religious reverence, for he did not know the quality of his guests; but through the customary form of civility. See on verses Gen 18:3-5 (note) of the preceding chapter.

And there came two angels to Sodom at even,.... Or "the two angels" (h), the two men who were angels in the likeness of men, that had been with Abraham in the heat of the day at Hebron, on the evening of the same day came to Sodom:

and Lot sat in the gate of Sodom: not as a civil magistrate to try causes there, being appointed a judge over them, as Jarchi relates; yea, the Jews say (i): that that day five judges were appointed by the men of Sodom, and Lot was the chief of them; but this is not likely, and seems to be contradicted, Gen 19:9; but he sat there to observe strangers that might pass by, and invite them into his house, and that they might not fall into the hands of the wicked Sodomites, who might abuse them; this being a time when not only travellers would be glad to put up and take refreshment, but his wicked neighbours lay in wait for them to satisfy their lusts on them: he had learnt this hospitality from Abraham:

and Lot seeing them, rose up to meet them: he arose from his seat and went forward to meet them, which showed his readiness and heartiness to receive them:

and he bowed himself with his face toward the ground; not in a religious way, as paying worship to angels, for as yet he did not know them to be such, and if he had, would not have given them divine adoration; but in a civil way, as was the custom of the eastern countries to bow very low in their civil respects to men, especially to great personages; and such Lot took these to be by their goodly looks and by their dress, as appears by his salutation of them in Gen 19:2.
