Luke 13:18-21

18 He said therefore, "What is the kingdom of God like? And to what should I compare it?
19 It is like a mustard seed that someone took and sowed in the garden; it grew and became a tree, and the birds of the air made nests in its branches."
20 And again he said, "To what should I compare the kingdom of God?
21 It is like yeast that a woman took and mixed in with three measures of flour until all of it was leavened."
