Matthew 13:31-41

31 Another parable set he before them, saying, The kingdom of heaven is like unto a grain of mustard seed, which a man took, and sowed in his field:
32 which indeed is less than all seeds; but when it is grown, it is greater than the herbs, and becometh a tree, so that the birds of the heaven come and lodge in the branches thereof.
33 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 it was all leavened.
34 All these things spake Jesus in parables unto the multitudes; and without a parable spake he nothing unto them:
35 that it might be fulfilled which was spoken through the prophet, saying, I will open my mouth in parables; I will utter things hidden from the foundation of the world.
36 Then he left the multitudes, and went into the house: and his disciples came unto him, saying, Explain unto us the parable of the tares of the field.
37 And he answered and said, He that soweth the good seed is the Son of man;
38 and the field is the world; and the good seed, these are the sons of the kingdom; and the tares are the sons of the evil [one];
39 and the enemy that sowed them is the devil: and the harvest is the end of the world; and the reapers are angels.
40 As therefore the tares are gathered up and burned with fire; so shall it be in the end of the world.
41 The Son of man shall send forth his angels, and they shall gather out of his kingdom all things that cause stumbling, and them that do iniquity,
