What does Judges 8:35 mean?
Gideon's story ends with a description of the three sins the people of Israel took up after his death (Judges 8:29–32). First, they immediately returned to the worship of the false gods known as the Baals. Second, they set aside honor for the Lord (Judges 8:33–34). They stopped worshiping the only true God (Exodus 3:15) who had saved them repeatedly.Finally, the people of Israel turned their backs on Gideon's family. They didn't show them the same love they had shown to Gideon. They didn't honor all the good he had done for Israel, in the power of the Lord, by continuing to do good to his family.
That sudden, callous change might have inspired the tragic events which follow. One of Gideon's sons, Abimelech, will bring the rest of his family to ruin, as described in the following chapter. Nobody in Israel will rise to save or avenge them. God will do so Himself.
