'One of the Least of These' in the Bible

Whoever therefore shall break one of the least of these commandments, and teach men so, shall be called least in the kingdom of heaven; but whoever shall do and teach, he shall be called great in the kingdom of heaven.

And the king shall answer and say to them, I tell you truly, that inasmuch as you have done it to one of the least of these my brothers, you have done it to me.

Then he shall answer them saying, I tell you truly, that inasmuch as you have not done it to one of the least of these my brothers, you have not done it to me.
