Judges 17:13

Now know I that the Lord will do me good - As he had already provided an epitome of the tabernacle, a model of the ark, mercy-seat, and cherubim; and had got proper sacerdotal vestments, and a Levite to officiate; he took for granted that all was right, and that he should now have the benediction of God. Some think that he expected great gain from the concourse of the people to his temple; but of this there is no evidence in the text. Micah appears to have been perfectly sincere in all that he did.

I Have already remarked that there is no positive evidence that Micah or his mother intended to establish any idolatrous worship. Though they acted without any Divine command in what they did; yet they appear, not only to have been perfectly sincere, but also perfectly disinterested. They put themselves to considerable expense to erect this place of worship, and to maintain, at their own proper charges, a priest to officiate there; and without this the place, in all probability, would have been destitute of the worship and knowledge of the true God. His sincerity, disinterestedness, and attachment to the worship of the God of his fathers, are farther seen in the joy which he expressed on finding a Levite who might legally officiate in his house. It is true, he had not a Divine warrant for what he did; but the state of the land, the profligacy of his countrymen, his distance from Shiloh, etc., considered, he appears to deserve more praise than blame, though of the latter he has received a most liberal share from every quarter. This proceeds from that often-noticed propensity in man to take every thing which concerns the character of another by the worst handle. It cannot be considered any particular crime, should these notes be found at any time leaning to the other side.

This shows the ignorance as well as the superstition of the age (compare 2 Kings 18:22), and gives a picture of the lawlessness of the times. The incidental testimony to the Levitical priesthood is to be noted; but the idolatrous worship in the immediate neighborhood of Shiloh is passing strange.

17:13 Do me good - I am assured God will bless me. So blind and grossly partial he was in his judgment, to think that one right circumstance would answer for all his substantial errors, in making and worshipping images against God's express command, in worshipping God in a forbidden place, by a priest illegally appointed.
