'Little Faith' in the Bible

Now: if God so clothe the grass of the field, which to day is, and to morrow is cast into the still, will he not much more clothe you, O ye of little faith?

And he saith to them, Why are ye fearful, O ye of little faith? Then arising, he rebuked the winds and the sea, and there was a great calm.

And immediately Jesus reaching forth his hand, caught him, and saith to him, O thou of little faith, wherefore didst thou doubt?

Jesus knowing it said to them, O ye of little faith, why reason ye among yourselves, because ye have taken no bread?

If then God so cloth the grass, which is to day in the field, and to morrow is cast into the still, how much more will he clothe you, O ye of little faith?
