'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 offend one of these little ones which believe in me, it were better for him that a millstone were hanged about his neck, and that he were drowned in the depth of the sea.

Take heed 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 which is in heaven.

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

But He said, “Leave the children alone, and do not forbid them from coming to Me; for the kingdom of heaven belongs to such as these.”
