Judges 8:30-35

He had seventy sons of his own, because he had many wives. He had a slave woman who lived in Shechem, and he had a son by her, whom he named Abimelech. So Gideon son of Joash died at a good old age. He was buried in the tomb of Joash, his father, in Ophrah, where the Abiezrites live. As soon as Gideon died, the people of Israel were again unfaithful to God and followed the Baals. They made Baal-Berith their god. The Israelites did not remember the LORD their God, who had saved them from all their enemies living all around them. And they were not kind to the family of Jerub-Baal, also called Gideon, for all the good he had done for Israel.
