Matthew 13:37 (KJV)

Which indeed is the least of all seeds: but when it is grown, it is the greatest among herbs, and becometh a tree, so that the birds of the air come and lodge in the branches thereof.

Another parable spake he unto them; The kingdom of heaven is like unto leaven, which a woman took, and hid in three measures of meal, till the whole was leavened.

All these things spake Jesus unto the multitude in parables; and without a parable spake he not unto them:

That it might be fulfilled which was spoken by the prophet, saying, I will open my mouth in parables; I will utter things which have been kept secret from the foundation of the world.

Then Jesus sent the multitude away, and went into the house: and his disciples came unto him, saying, Declare unto us the parable of the tares of the field.

The field is the world; the good seed are the children of the kingdom; but the tares are the children of the wicked one;

The enemy that sowed them is the devil; the harvest is the end of the world; and the reapers are the angels.

As therefore the tares are gathered and burned in the fire; so shall it be in the end of this world.

The Son of man shall send forth his angels, and they shall gather out of his kingdom all things that offend, and them which do iniquity;

And shall cast them into a furnace of fire: there shall be wailing and gnashing of teeth.
