Luke 13:18-21

He said therefore, Unto what is the kingdom of God like? and whereunto shall I liken it? It is like unto a grain of mustard seed, which a man took, and cast into his own garden; and it grew, and became a tree; and the birds of the heaven lodged in the branches thereof. And again he said, Whereunto shall I liken the kingdom of God? It is like unto leaven, which a woman took and hid in three measures of meal, till it was all leavened.
