Mentioned in the Bible by name

Gilead

And Jephthah (Hebr. Yiftach), the Gileadite, was a mighty warrior, but he was the son of a prostitute, and Gilead gave birth to Jephthah.
[The name Jephthah (Hebr. Yiftach) means "he has opened." The name seems to express his mother's joy at having given birth to a son. However, it is not entirely clear who "he" refers to, but it probably refers to some deity who has opened her womb. The word is used for a place called Jiftach-el (Josh. 19:14, 27) where the general name for God (Hebr. El) is used. One possibility is that Jiftach's name is "Jiftach-El" or "Jiftach-Yahweh," i.e., that it refers to the God of Israel, but based on the story, this is unfortunately unlikely. His name was perhaps rather "Jephthah-Baal." His mother's occupation, his father's actions, his half-brothers' character, and Jephthah's own actions point to a strong influence of Canaanite culture and religion.]

And Gilead's wife bore him sons, and when his wife's sons grew up, they drove Jephthah away and said to him, "You shall not inherit our father's house, for you are the son of another woman." Jephthah's mother may have been an Israelite, but more likely a Canaanite, perhaps a temple prostitute. When Jephthah's father dies and it is time to divide the inheritance, his half-brothers drive him away because they do not want to share the inheritance with him.
