'Mustard' in the Bible

He put another story before them, saying, The kingdom of heaven is like a grain of mustard seed which a man took and put in his field:

And he says to them, Because of your little faith: for truly I say to you, If you have faith as a grain of mustard seed, you will say to this mountain, Be moved from this place to that; and it will be moved; and nothing will be impossible to you.

It is like a grain of mustard seed, which, when it is put in the earth, is smaller than all the seeds on the earth,

It is like a grain of mustard seed which a man took and put in his garden, and it became a tree, and the birds of heaven made their resting-places in its branches.

And the Lord said, If your faith was only as great as a grain of mustard seed, you might say to this tree, Be rooted up and planted in the sea; and it would be done.
