'Little Ones' in the Bible

And whoever in the name of a disciple gives to one of these little ones even a cup of cold water to drink, truly I say to you, he shall not lose his reward.”

but whoever causes one of these little ones who believe in Me to stumble, it would be better for him to have a heavy millstone hung around his neck, and to be drowned in the depth of the sea.

“See that you do not despise one of these little ones, for I say to you that their angels in heaven continually see the face of My Father who is in heaven.

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