Genesis 19:6
“Lot went out to them to the door, and shut the door after him.”
What does Genesis 19:6 mean?
Lot is stepping outside to meet the men (who are actually angels) at his doorway, then closing the door behind him. He's doing this to shield his family from these strangers, which was an important duty of hospitality in that ancient culture. In the crisis unfolding around Sodom, this moment shows Lot trying to protect his household while still taking responsibility for what happens at his threshold, even though the danger he's about to face is far worse than he realizes.
