Judges 8:30-35

He had seventy sons of his own, for he had many wives. His concubine, who lived in Shechem, also bore him a son, whom he named Abimelek. Gideon son of Joash died at a good old age and was buried in the tomb of his father Joash in Ophrah of the Abiezrites. No sooner had Gideon died than the Israelites again prostituted themselves to the Baals. They set up Baal-Berith as their god and did not remember the LORD their God, who had rescued them from the hands of all their enemies on every side. They also failed to show any loyalty to the family of Jerub-Baal (that is, Gideon) in spite of all the good things he had done for them.
