'One of the Least of These' in the Bible

Therefore if any one may break one of the least of these commandments, and so teach the people, he shall be called the least in the kingdom of the heavens: but whosoever may do and teach them, the same shall be called great in the kingdom of the heavens.

And the King responding will say unto them, Truly I say unto you, Inasmuch as ye did these things to one of the least of these my brethren, you did them unto me.

Then will He respond to them, saying, Truly I say unto you, Inasmuch as you did not these things to one of the least of these, you did them not unto me.
