61 Then the children of Israel did evil in the sight of the Lord. So the Lord delivered them into the hand of Midian for seven years, 2 and the hand of Midian prevailed against Israel. Because of the Midianites, the children of Israel made for themselves the dens, the caves, and the strongholds which are in the mountains.
Matthew Henry's Commentary on Judges 6:1-2
Commentary on Judges 6:1-6
(Read Judges 6:1-6)
Israel's sin was renewed, and Israel's troubles were repeated. Let all that sin expect to suffer. The Israelites hid themselves in dens and caves; such was the effect of a guilty conscience. Sin dispirits men. The invaders left no food for Israel, except what was taken into the caves. They prepared that for Baal with which God should have been served, now God justly sends an enemy to take it away in the season thereof.
