Matthew 13:31-32 - The Parable Of The Mustard Seed
31 Another parable set he before them, saying, The kingdom of heaven is like unto a grain of mustard seed, which a man took, and sowed in his field: 32 which indeed is less than all seeds; but when it is grown, it is greater than the herbs, and becometh a tree, so that the birds of the heaven come and lodge in the branches thereof.
30 And he said, How shall we liken the kingdom of God? or in what parable shall we set it forth? 31 It is like a grain of mustard seed, which, when it is sown upon the earth, though it be less than all the seeds that are upon the earth, 32 yet when it is sown, groweth up, and becometh greater than all the herbs, and putteth out great branches; so that the birds of the heaven can lodge under the shadow thereof.
33 And with many such parables spake he the word unto them, as they were able to hear it; 34 and without a parable spake he not unto them: but privately to his own disciples he expounded all things.
