Read Judges 11:2 Using Other Translations
And Gilead's wife bare him sons; and his wife's sons grew up, and they thrust out Jephthah, and said unto him, Thou shalt not inherit in our father's house; for thou art the son of a strange woman.
And Gilead's wife also bore him sons. And when his wife's sons grew up, they drove Jephthah out and said to him, "You shall not have an inheritance in our father's house, for you are the son of another woman."
Gilead’s wife also had several sons, and when these half brothers grew up, they chased Jephthah off the land. “You will not get any of our father’s inheritance,” they said, “for you are the son of a prostitute.”
