Judges 11:1-2

1Now Jephthah the Gileadite was a brave warrior, but he was the son of a prostitute. Gilead was the father of Jephthah.

2Gilead’s wife 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, because you are the son of another woman.”
