'One of the Least of These' in the Bible

Yea out of one of the least of these horns, there came up yet another horn, which waxed marvelous great: toward the south, toward the east, and toward the fair pleasant land.

Therefore whoever abolishes one of the least of these commandments and teaches people to do so will be called least in the kingdom of heaven, but whoever keeps [them] and teaches [them], this person will be called great in the kingdom of heaven.

And the King shall answer and say unto them, Verily I say unto you, Inasmuch as ye have done it unto one of the least of these my brethren, ye have done it unto me.

Then shall he answer them, saying, Verily I say unto you, Inasmuch as ye did it not to one of the least of these, ye did it not to me.
