It is like a grain of mustard seed, which a man took, and cast into his garden; and it grew, and waxed a great tree; and the fowls of the air lodged in the branches of it.

This verse says that a tiny mustard seed was planted in a garden, and it grew very big. Birds then made their homes in its branches.
