Matthew 13:31-32 - The Parable Of The Mustard Seed
31 He put before them another parable, saying, "The kingdom of heaven is like a mustard seed that a man took [and] sowed in his field. 32 {It} is the smallest of all the seeds, but when it is grown it is larger than the garden herbs and becomes a tree, so that the birds of the sky come and nest in its branches."
30 And he said, "With what can we compare the kingdom of God, or by what parable can we present it? 31 [It is] like a mustard seed that when sown on the ground, [although it] is the smallest of all the seeds that [are] on the ground, 32 but when it is sown it grows up and becomes the largest of all the garden herbs, and sends out large branches so that the birds of the sky are able to nest in its shade."
33 And with many parables such as these he was speaking the word to them, as they were able to hear [it]. 34 And he did not speak to them without a parable, but in private he explained everything to his own disciples.
