“Jerubbaal son of Joash went to live in his own house. Now Gideon had seventy sons, his own offspring, for he had many wives. His concubine who was in Shechem also bore him a son. He named him name Abimelech. Then Gideon son of Joash died at a good old age. He was buried in the tomb of his father Joash at Ophrah of the Abiezrites.”
Gideon had 70 sons, not counting the daughters, since he had many wives. As if he did not have enough wives he also had a concubine who bore him a son called Abimelech, who will play a major role, among all these children of Gideon. He died of a good age without any specific number attached to it. He was buried in the tomb of his father at Ophrah.
