'Least' in the Bible

I say to you, Among all the sons of women, not one is greater than John: but he who is least in the kingdom of God is greater than he.

And said to them, Whoever gives honour to this child in my name, gives honour to me: and whoever gives honour to me, gives honour to him who sent me: for whoever is least among you all, that man is great.

If, then, you are not able to do even that which is least, why are you troubled about the rest?

But Jesus, answering, said, Put up with this, at least. And touching his ear, he made it well.
