He set another parable before them, saying, “The Kingdom of Heaven is like a grain of mustard seed, which a man took, and sowed in his field; which indeed is smaller than all seeds. But when it is grown, it is greater than the herbs, and becomes a tree, so that the birds of the air come and lodge in its branches.” He spoke another parable to them. “The Kingdom of Heaven is like yeast, which a woman took, and hid in three measuresof meal, until it was all leavened.”
