I hasten to close the awful account of this tribe, for nothing can give a more horrible description of their degeneracy, than that as soon as they had conquered Laish, and settled themselves in their new city of Dan, they set up public idolatry. Whether this Jonathan was the Levite of Micah, and now called for the first time by his name, is not said. But I rather incline to think not. It is not probable, that the Holy Ghost would close his character with the record of his name, who had thus become the wretched instrument of establishing idolatry in one of the tribes of Israel. Of all such little mention is made in the sacred word, for the most part their memorial is perished with them.
Judges 18:27-31
27 And they took the things which Micah had made, and the priest which he had, and came unto Laish, unto a people that were at quiet and secure: and they smote them with the edge of the sword, and burnt the city with fire.
28 And there was no deliverer, because it was far from Zidon, and they had no business with any man; and it was in the valley that lieth by Bethrehob. And they built a city, and dwelt therein.
29 And they called the name of the city Dan, after the name of Dan their father, who was born unto Israel: howbeit the name of the city was Laish at the first.
30 And the children of Dan set up the graven image: and Jonathan, the son of Gershom, the son of Manasseh, he and his sons were priests to the tribe of Dan until the day of the captivity of the land.
31 And they set them up Micah's graven image, which he made, all the time that the house of God was in Shiloh.
