Judges 17:12

‘ And Micah installed (filled the hand of) the Levite, and the young man became his priest, and was in the house of Micah.'

The Levite was installed as priest in Micah's house of God. Strictly of course he should have pointed out where Micah was going amiss, but instead he appears to have gone along with the arrangements, thus confirming to Micah's satisfaction that Micah was on the right lines. However there are grounds for thinking that the rigid requirements of Yahwism were being softened by the syncretism of the age which may well have affected the Levite's views.
