Heb 11:32-33
In the Old Testament, Gideon was able to defeat his enemies by believing in God and the Christ to come.
Judg 6:34 But the Spirit of the Lord came upon Gideon, and he blew a trumpet; and Abiezer was gathered after him.
Heb 11:32 And what shall I more say? for the time would fail me to tell of Gedeon, and of Barak, and of Samson, and of Jephthae; of David also, and Samuel, and of the prophets: 33 Who through faith subdued kingdoms, wrought righteousness, obtained promises, stopped the mouths of lions.
