Mark 4:30-34
And He said, “How shall we picture the kingdom of God, or by what parable shall we present it? It is like a mustard seed, which, when sown upon the soil, though it is smaller than all the seeds that are upon the soil, yet when it is sown, it grows up and becomes larger than all the garden plants and forms large branches; so that the birds of the air can nest under its shade.”
With many such parables He was speaking the word to them, so far as they were able to hear it; and He did not speak to them without a parable; but He was explaining everything privately to His own disciples.
Luke 13:18-21
So He was saying, “What is the kingdom of God like, and to what shall I compare it? It is like a mustard seed, which a man took and threw into his own garden; and it grew and became a tree, and the birds of the air nested in its branches.”
And again He said, “To what shall I compare the kingdom of God? It is like leaven, which a woman took and hid in three pecks of flour until it was all leavened.”
Matthew 13:31-52
He presented another parable to them, saying, “The kingdom of heaven is like a mustard seed, which a man took and sowed in his field; and this is smaller than all other seeds, but when it is full grown, it is larger than the garden plants and becomes a tree, so that the birds of the air come and nest in its branches.”
He spoke another parable to them, “The kingdom of heaven is like leaven, which a woman took and hid in three pecks of flour until it was all leavened.”
All these things Jesus spoke to the crowds in parables, and He did not speak to them without a parable. This was to fulfill what was spoken through the prophet:
“I will open My mouth in parables;
I will utter things hidden since the foundation of the world.”
Then He left the crowds and went into the house. And His disciples came to Him and said, “Explain to us the parable of the tares of the field.” And He said, “The one who sows the good seed is the Son of Man, and the field is the world; and as for the good seed, these are the sons of the kingdom; and the tares are the sons of the evil one; and the enemy who sowed them is the devil, and the harvest is the end of the age; and the reapers are angels. So just as the tares are gathered up and burned with fire, so shall it be at the end of the age. The Son of Man will send forth His angels, and they will gather out of His kingdom all stumbling blocks, and those who commit lawlessness, and will throw them into the furnace of fire; in that place there will be weeping and gnashing of teeth. Then the righteous will shine forth as the sun in the kingdom of their Father. He who has ears, let him hear.
“The kingdom of heaven is like a treasure hidden in the field, which a man found and hid again; and from joy over it he goes and sells all that he has and buys that field.
“Again, the kingdom of heaven is like a merchant seeking fine pearls, and upon finding one pearl of great value, he went and sold all that he had and bought it.
“Again, the kingdom of heaven is like a dragnet cast into the sea, and gathering fish of every kind; and when it was filled, they drew it up on the beach; and they sat down and gathered the good fish into containers, but the bad they threw away. So it will be at the end of the age; the angels will come forth and take out the wicked from among the righteous, and will throw them into the furnace of fire; in that place there will be weeping and gnashing of teeth.
“Have you understood all these things?” They said to Him, “Yes.” And Jesus said to them, “Therefore every scribe who has become a disciple of the kingdom of heaven is like a head of a household, who brings out of his treasure things new and old.”
