Judges 11:1-3

Now Jephthah the Gileadite was a mighty man of valor, but he was the son of a harlot; and Gilead begot Jephthah. Gilead’s wife bore sons; and when his wife’s sons grew up, they drove Jephthah out, and said to him, “You shall have no inheritance in our father’s house, for you are the son of another woman.” Then Jephthah fled from his brothers and dwelt in the land of Tob; and worthless men banded together with Jephthah and went out raiding with him.
