Matthew 13:31-32 - The Parable Of The Mustard Seed
31 He put another parable before them. "The Realm of heaven," he said, "is like a grain of mustard-seed which a man takes and sows in his field. 32 It is less than any seed on earth, but when it grows up it is larger than any plant, it becomes a tree, so large that the wild birds come and roost in its branches."
30 He said also, "To what can we compare the Realm of God? how are we to put it in a parable? 31 It is like a grain of mustard-seed ??less than any seed on earth when it is sown on earth; 32 but once sown it springs up to be larger than any plant, throwing out such big branches that the wild birds can roost under its shadow."
33 In many a parable like this he spoke the word to them, so far as they could listen to it; 34 he never spoke to them except by way of parable, but in private he explained everything to his own disciples.
