Judges 8:29-31

Wycliffe Bible

²⁹ And so Jerubbaal, the son of Joash, went, and dwelled in his house;

³⁰ and he had seventy sons, that went out of his thigh, for he had many wives.

³¹ And a concubine, that is, (the) secondary wife, of him, whom he had in Shechem, engendered to him a son, Abimelech by name.
