'Cowards' in the Bible

He asked them, "Why are you such cowards? Don't you have any faith yet?"

Therefore, being engaged in this service and being mindful of the mercy which has been shown us, we are not cowards.

Therefore we are not cowards. Nay, even though our outward man is wasting away, yet our inward man is being renewed day by day.

But the cowards, unbelievers, vile, murderers, sexually immoral, sorcerers, idolaters, and all liars—their share will be in the lake that burns with fire and sulfur, which is the second death.”
