Albert Barnes Commentary Judges 4:8

"And Barak said unto her, If thou wilt go with me, then I will go; but if thou wilt not go with me, I will not go." — Judges 4:8 (ASV)

Barak, like Gideon (Judges 6:15, 36, 40), and Abraham (Genesis 15:2–3; Genesis 17:18), and Moses (Exodus 4:10, 13), and Peter (Matthew 14:30–31), exhibited some weakness of faith at first. But this only makes his example more profitable for our encouragement, though he himself suffered some loss by his weakness (Judges 4:9).
