'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.

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 to me.'

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