'Little Ones' in the Bible

And whosoever shall give to drink to one of these little ones a cup of cold water only, in the name of a disciple, verily I say unto you, he shall in no wise lose his reward.

But whosoever shall offend one of these little ones who believe in me, it were profitable for him that a great millstone had been hanged upon his neck and he be sunk in the depths of the sea.

See that ye do not despise one of these little ones; for I say unto you that their angels in the heavens continually behold the face of my Father who is in the heavens.

So it is not the will of your Father who is in the heavens that one of these little ones should perish.
