And Lot went out at the door unto them,.... At the door of his house:

and shut the door after him; the door of the passage to his house, the courtyard door, for another word is here used; unless the one was properly the door, and the other a hatch: however, this precaution of shutting it was used to prevent the men of Sodom rushing in, and taking away the men by violence; and that Lot might have some opportunity of trying what he could do by arguments, to prevail upon them to desist from their attempt.

Lot went out to them, shut the door behind him to protect his guests, and offered to give his virgin daughters up to them. "Only to these men (האל, an archaism for האלּה rof, occurs also in Genesis 19:25; Genesis 26:3-4; Leviticus 18:27, and Deuteronomy 4:42; Deuteronomy 7:22; Deuteronomy 19:11; and אל for אלּה in 1 Chronicles 20:8) do nothing, for therefore (viz., to be protected from injury) have they come under the shadow of my roof." In his anxiety, Lot was willing to sacrifice to the sanctity of hospitality his duty as a father, which ought to have been still more sacred, "and committed the sin of seeking to avert sin by sin." Even if he expected that his daughters would suffer no harm, as they were betrothed to Sodomites (Genesis 19:14), the offer was a grievous violation of his paternal duty. But this offer only heightened the brutality of the mob. "Stand back" (make way, Isaiah 49:20), they said; "the man, who came as a foreigner, is always wanting to play the judge" (probably because Lot had frequently reproved them for their licentious conduct, 2 Peter 2:7, 2 Peter 2:8): "not will we deal worse with thee than with them." With these words they pressed upon him, and approached the door to break it in. The men inside, that is to say, the angels, then pulled Lot into the house, shut the door, and by miraculous power smote the people without with blindness (סנורים here and 2 Kings 6:18 for mental blindness, in which the eye sees, but does not see the right object), as a punishment for their utter moral blindness, and an omen of the coming judgment.

And Lot went out at the door unto them, and shut the door after him,

19:1-29 Lot was good, but there was not one more of the same character in the city. All the people of Sodom were very wicked and vile. Care was therefore taken for saving Lot and his family. Lot lingered; he trifled. Thus many who are under convictions about their spiritual state, and the necessity of a change, defer that needful work. The salvation of the most righteous men is of God's mercy, not by their own merit. We are saved by grace. God's power also must be acknowledged in bringing souls out of a sinful state If God had not been merciful to us, our lingering had been our ruin. Lot must flee for his life. He must not hanker after Sodom. Such commands as these are given to those who, through grace, are delivered out of a sinful state and condition. Return not to sin and Satan. Rest not in self and the world. Reach toward Christ and heaven, for that is escaping to the mountain, short of which we must not stop. Concerning this destruction, observe that it is a revelation of the wrath of God against sin and sinners of all ages. Let us learn from hence the evil of sin, and its hurtful nature; it leads to ruin.
