Judges 11:2

And Gilead's wife bare him sons; and his wife's sons grew up, and they thrust out Jephthah, expelled him from the home as not on the same level with them, and said unto him, Thou shalt not inherit in our father's house; for thou art the son of a strange woman, of one who was not properly a wife, even in the sense of a concubine, the stain resting upon his birth excluded him from the rights of a child in the family.
