John Gill Bible Commentary

And the man departed out of the city from Bethlehemjudah, to sojourn where he could find a place,.... Either being a man that had a rambling head, and of an unsettled mind, and could not easily fix any where; or else there being no supreme magistrate, to take care that the Levites had their due maintenance, for which there was a sufficient provision made by law; and the people being negligent of paying their tithes, there being none to oblige them to it, and they indifferent to the true worship of God, and prone to idolatry; this man was obliged to go abroad, and seek for a livelihood where he could get it, and sojourn in a place the most convenient for him: and he came to Mount Ephraim, to the house of Micah, as he journeyed: not with a design to stay there, but called by the way, having heard perhaps that Micah was both a wealthy and an hospitable man, and he also might have heard of the new form of worship he had set up in his house.
