'Mustard' in the Bible

He gave them another parable [to consider], saying, “The kingdom of heaven is like a mustard seed, which a man took and sowed in his field;

He answered, “Because of your little faith [your lack of trust and confidence in the power of God]; for I assure you and most solemnly say to you, if you have [living] faith the size of a mustard seed, you will say to this mountain, ‘Move from here to there,’ and [if it is God’s will] it will move; and nothing will be impossible for you.

It is like a mustard seed, which, when it is sown on the ground, even though it is smaller than all the [other] seeds that are [sown] on the soil,

It is like a mustard seed, which a man took and planted in his own garden; and it grew and became a tree, and the birds of the sky found shelter and nested in its branches.”

And the Lord said, “If you have [confident, abiding] faith in God [even as small] as a mustard seed, you could say to this mulberry tree [which has very strong roots], ‘Be pulled up by the roots and be planted in the sea’; and [if the request was in agreement with the will of God] it would have obeyed you.
