Sufficiency of Scripture

He spoke another parable to them, “ The kingdom of heaven is like leaven, which a woman took and hid in three pecks of flour until it was all leavened.”

All these things Jesus spoke to the crowds in parables, and He did not speak to them without a parable. This was to fulfill what was spoken through the prophet:

“ I will open My mouth in parables;
I will utter things hidden since the foundation of the world.”

Matthew 13:33-35
