Judges 8:29-35 ESV
Jerubbaal the son of Joash went and lived in his own house. Now Gideon had seventy sons, his own offspring, for he had many wives. And his concubine who was in Shechem also bore him a son, and he called his name Abimelech. And Gideon the son of Joash died in a good old age and was buried in the tomb of Joash his father, at Ophrah of the Abiezrites.
As soon as Gideon died, the people of Israel turned again and whored after the Baals and made Baal-berith their god. And the people of Israel did not remember the LORD their God, who had delivered them from the hand of all their enemies on every side, and they did not show steadfast love to the family of Jerubbaal (that is, Gideon) in return for all the good that he had done to Israel.
