Another story by way of comparison He [Jesus] set forth
before them, saying,
The kingdom of heaven is like a grain of mustard seed, which a man took and sowed in his field.
(32) Of all the seeds it is the smallest, but when it has grown it is the largest of the garden herbs and
becomes a tree, so that the birds of the air come and find shelter in its branches.
~Matthew 13:31-32 (Bible)
