Hebrews 11:32-34
32 And what more shall I say? For time will fail me if I tell of Gideon, Barak, Samson, Jephthah, of David and Samuel and the prophets, 33 who by faith conquered kingdoms, performed acts of righteousness, obtained promises, shut the mouths of lions, 34 quenched the power of fire, escaped the edge of the sword, from weakness were made strong, became mighty in war, put foreign armies to flight.

Judges 11:1-11 (NASB)
Now Jephthah the Gileadite was a valiant warrior, but he was the son of a harlot. And Gilead was the father of Jephthah. 2 Gilead’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, for you are the son of another woman.” 3 So Jephthah fled from his brothers and lived in th e land of Tob; and worthless fellows gathered themselves about Jephthah, and they went out with him. 4 It came about after a while that the sons of Ammon fought against Israel. 5 When the sons of Ammon fought against Israel, the elders of Gilead went to get Jephthah from the land of Tob; 6 and they said to Jephthah, “Come and be our chief that we may fight against the sons of Ammon.” 7 Then Jephthah said to the elders of Gilead, “Did you not hate me and drive me from my father’s house? So why have you come to me now when you are in trouble?” 8 The elders of Gilead said to Jephthah, “For this reason we have now returned to you, that you may go with us and fight with the sons of Ammon and become head over all the inhabitants of Gilead.” 9 So Jephthah said to the elders of Gilead, “If you take me back to fight against the sons of Ammon and the LORD gives them up to me, will I become your head?” 10 The elders of Gilead said to Jephthah, “The LORD is witness between us; surely we will do as you have said.” 11 Then Jephthah went with the elders of Gilead, and the people made him head and chief over them; and Jephthah spoke all his words before the LORD

1 Samuel 12:11 (NASB)
11 Then the LORD sent Jerubbaal and Bedan and Jephthah and Samuel, and delivered you from the hands of your enemies all around, so that you lived in security.

Hebrews 11:1-3 (NASB)
Now faith is the assurance of things hoped for, the [c]conviction of things not seen. 2 For by it the men of old gained approval. 3 By faith we understand that the worlds were prepared by the word of God, so that what is seen was not made out of things which are visible.
