When reading the book of Judges, one can hardly miss the line “the Israelites did evil in the eyes of the LORD” because it keeps repeating. The other line that is repeated is “in those days Israel had no king; everyone did as he saw fit”.
Matthew Henry in his commentary described the relationship between the 2 lines as “every man did that which was right in his own eyes, and then they soon did that which was evil in the sight of the LORD“. To be frank, when I read the passages related to “everyone did as he saw fit”, I hardly think what was done was right.
These 2 lines teach us that there are things that we do that seem right to us, but it may not be so to the LORD, and it might even be seen as evil.
