Mustard Seed

Matthew 13:31-32
[13:31] Another parable put he forth unto them, saying, The kingdom of heaven is like to a grain of mustard seed, which a man took, and sowed in his field: [32] Which indeed is the least of all seeds: but when it is grown, it is the greatest among herbs, and becometh a tree, so that the birds of the air come and lodge in the branches thereof.

Mark 4:30-32
[4:30] And he said, Whereunto shall we liken the kingdom of God? or with what comparison shall we compare it? [31] It is like a grain of mustard seed, which, when it is sown in the earth, is less than all the seeds that be in the earth: [32] But when it is sown, it groweth up, and becometh greater than all herbs, and shooteth out great branches; so that the fowls of the air may lodge under the shadow of it.

Luke 13:18-19
[13:18] Then said he, Unto what is the kingdom of God like? and whereunto shall I resemble it? [19] It is like a grain of mustard seed, which a man took, and cast into his garden; and it grew, and waxed a great tree; and the fowls of the air lodged in the branches of it.
