Luke 13:18-19 [ The Parables of the Mustard Seed and the Yeast ] Then Jesus asked, “What is the kingdom of God like? What shall I compare it to? It is like a mustard seed, which a man took and planted in his garden. It grew and became a tree, and the birds perched in its branches.”

Luke 17:6 He replied, “If you have faith as small as a mustard seed, you can say to this mulberry tree, ‘Be uprooted and planted in the sea,’ and it will obey you.
