What does Judges 8:34 mean?
Following the death of God's deliverer, Gideon (Judges 8:32–33), the people of Israel began to sin in three specific ways. First, as described in the previous verse, they became unfaithful to the Lord. They once more worshipped the Canaanite deities known as Baals. They made a god known as Baal-berith their god in place of the One True God (Exodus 3:15; 20:1–6).Second, in this verse, they once again forgot the Lord—they failed to "remember" Him. This implies an intentional setting aside of something. It doesn't mean they became unaware of God's existence or lost all memory of what had happened in the past. Rather, it means they stopped thinking those things mattered. They lived as if He didn't exist and worshipped as if He was not real.
The third sin is mentioned in the following verse: callousness to Gideon's surviving family (Judges 8:35).
