Matthew 13:31-32 - The Parable Of The Mustard Seed
31 Another parable he proposed to them, saying, The kingdom of heaven is like a grain of mustard, which a man took and sowed in his field: 32 which indeed is among the smallest of all seeds; but when it is grown, it is among the greatest of herbs, and becomes a tree, so that the birds of the air come and make their nests in the branches of it.
30 And he said, To what shall I liken the kingdom of God, and under what parabolic figure shall I represent it? 31 It is like a grain of mustard, which when it is sown in the earth, is among the least of all the seeds which are upon the earth: 32 but when it is sown, it groweth up and becomes greater than all herbaceous plants, and produceth vast branches; so that the birds of the air may roost under the shadow of it.
33 And with many such like parables spake he to them the word. 34 And without a parable spake he not unto them; but in private he explained them all to his disciples.
