'Least of These' in the Bible

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 will answer [and] say to them, 'Truly I say to you, in as much as you did [it] to one of the least of these brothers of mine, you did [it] to me.'

Then he will answer them, saying, 'Truly I say to you, in as much as you did not do [it] to one of the least of these, you did not do [it] to me.'
