Luke 13:18-21
The Mustard Seed and the Leaven
18 He said therefore, “What is the kingdom of God like? And to what shall I compare it? 19 It is like a grain of mustard seed that a man took and sowed in his garden, and it grew and became a tree, and the birds of the air made nests in its branches.”
20 And again he said, “To what shall I compare the kingdom of God? 21 It is like leaven that a woman took and hid in three measures of flour, until it was all leavened.”
