'Little Ones' in the Bible

And whosoever shall give to drink unto 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 whoso shall cause one of these little ones that believe on me to stumble, it is profitable for him that a great millstone should be hanged about his neck, and that he should be sunk in the depth of the sea.

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

Even so it is not the will of your Father who is in heaven, that one of these little ones should perish.
