The children of Dan set up for themselves the engraved image: and Jonathan, the son of Gershom, the son of Moses, he and his sons were priests to the tribe of the Danites until the day of the captivity of the land.
This whole story of Micah and the Danites illustrates the terrible spiritual apostasy that corrupted Israel during the age of the judges. Even the grandson (or descendant) of Moses took leadership in it. It was no wonder that Israel had trouble with her external enemies (chs. 3-16) since she was so spiritually corrupt internally (chs. 17-18).
