Matthew 13:31-34

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.
