Matthew 13:31-32

Young's Literal Translation

³¹ Another simile he set before them, saying: `The reign of the heavens is like to a grain of mustard, which a man having taken, did sow in his field,

³² which less, indeed, is than all the seeds, but when it may be grown, is greatest of the herbs, and becometh a tree, so that the birds of the heaven do come and rest in its branches.'
