'You Of Little Faith' in the Bible

But if God so clothes the grass of the field, which is alive and green today and tomorrow is [cut and] thrown [as fuel] into the furnace, will He not much more clothe you? You of little faith!

He said to them, “Why are you afraid, you men of little faith?” Then He got up and rebuked the winds and the sea, and there was [at once] a great and wonderful calm [a perfect peacefulness].

Immediately Jesus extended His hand and caught him, saying to him, “O you of little faith, why did you doubt?”
