'He said, therefore, “What is the kingdom of God like, and what can I compare it to? It’s like a mustard seed that a man took and sowed in his garden. It grew and became a tree, and the birds of the sky nested in its branches.” Again he said, “What can I compare the kingdom of God to? It’s like leaven that a woman took and mixed into fifty pounds of flour until all of it was leavened.” '
