What does the Bible say about Jephthah?

In Judges 11:1, we learn that Jephthah was a Gileadite, described as a 'mighty man of valor.' His background was complex; he was the son of a harlot, which led to his rejection by his family. Despite this, Jephthah proved himself as a capable leader when called upon to defend Israel against the Ammonites. His life reflects the overarching biblical theme of God using imperfect individuals for His purpose, reminiscent of the greater Savior, Jesus Christ, who also faced rejection and yet was the mightiest of all.
