I. The people strove with the priests that should have taught them the knowledge of God; justly therefore were they destroyed for lack of knowledge, v. 6. Note, Those that rebel against the light can expect no other than to perish in the dark. Or it is a charge upon the priests, who should have been still teaching the people knowledge (Eccl. xii. 9), but they did not, or did it in such a manner that it was as if they had not done it at all, so there was no knowledge of God in the land; and because there was no vision, or none to any purpose, the people perished, Prov. xxix. 18. Note, Ignorance is so far from being the mother of devotion that it is the mother of destruction; lack of knowledge is ruining to any person or people. They are my people that are thus destroyed; their relation to God as his people aggravates both their sin in not taking pains to get the knowledge of that God whose command they were under and with whom they were taken into covenant, and likewise the sin of those who should have taught them; God set his children to school to them, and they never minded them nor took any pains with them.
