Matthew 13:31-33

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.”
