Judges 17:13
Ver. 13. Then said Micah,.... Within himself, pleased with what he had done, and with what he engaged in:
now know I that the Lord will do me good; that I shall enjoy his favour, be a happy man, and prosper; and by this it appears, that notwithstanding the idolatry he had fallen into, he had not utterly forsaken the Lord, but worshipped him in and by his images; there was a mixture of the worship of God, and of the worship of images:
seeing I have a Levite to my priest; who was of the same tribe the priests were, and so the nearest to them of any, and which he thought would be acceptable to God, and an omen of good to himself.
