Judges 1:17-19

Here we trace the want of faith, and consequently the want of courage, in Israel. What were the chariots of iron, when God fought the battles of Israel? But is not this, in a spiritual sense, the very case of Israel now? The faith of Peter could prompt him to attempt walking on the water, to come to Jesus, at his command. But we are told that when he saw the waves boisterous, his faith forsook him. Oh! for a portion of that faith which can quench the violence of fire, and out of weakness can make strong. Hebrews 11:34.
