Judges 17

7. Beth-lehem-judah--so called in contradistinction to a town of the same name in Zebulun ( Joshua 19:15 ).
of the family--that is, tribe.
of Judah--Men of the tribe of Levi might connect themselves, as Aaron did ( Exodus 6:23 ), by marriage with another tribe; and this young Levite belonged to the tribe of Judah, by his mother's side, which accounts for his being in Beth-lehem, not one of the Levitical cities.

8. the man departed . . . to sojourn where he could find a place--A competent provision being secured for every member of the Levitical order, his wandering about showed him to have been a person of a roving disposition or unsettled habits. In the course of his journeying he came to the house of Micah, who, on learning what he was, engaged his permanent services.

10. Micah said unto him, Dwell with me, and be unto me a father--a spiritual father, to conduct the religious services of my establishment. He was to receive, in addition to his board, a salary of ten shekels of silver.
a suit of apparel--not only dress for ordinary use, but vestments suitable for the discharge of his priestly functions.

12. Micah consecrated the Levite--Hebrew, "filled his hand." This act of consecration was not less unlawful for Micah to perform than for this Levite to receive

13. Now know I that the Lord will do me good--The removal of his son, followed by the installation of this Levite into the priestly office, seems to have satisfied his conscience, that by what he deemed the orderly ministrations of religion he would prosper. This expression of his hope evinces the united influence of ignorance and superstition.
