Matthew 13:31-33

31He gave them another parable [to consider], saying, “The kingdom of heaven is like a mustard seed, which a man took and sowed in his field;

32and of all the seeds [planted in the region] it is the smallest, but when it has grown it is the largest of the garden herbs and becomes a tree, so that the birds of the air find shelter in its branches.”

33He told them another parable, “The kingdom of heaven is like leaven, which a woman took and worked into three measures of flour until all of it was leavened.”
