Augustine of Hippo
Catena Aurea · Matthäusevangelium 13
Another parable spake he unto them; The kingdom of heaven is like unto leaven, which a woman took, and hid in three measures of meal, till the whole was leavened.
(Quæst. Ev. i. 12.) Or, The leaven signifies love, because it causes activity and fermentation; by the woman He means wisdom. By the three measures He intends either those three things in man, with the whole heart, with the whole soul, with the whole mind; or the three degrees of fruitfulness, the hundred-fold, the sixty-fold, the thirty-fold, or those three kinds of men, Noe, Daniel, and Job.
