So, I was reading again a passage that we used on Shabbat in a study of ‘chametz’ (leaven) and the uses of ‘unleavened’ in the Tanakh as well as the new Testament. Among others, we discussed a verse, Matthew 13:33, where Yeshua uses leavening as a positive image. On re-reading, the next two verses caught my eye.
33 He spoke another parable to them, “The kingdom of heaven is like leaven, which a woman took and hid in three [a]pecks of flour until it was all leavened.”
34 All these things Jesus
spoke to the crowds in parables, and He did not speak to them without a parable. 35 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.”
Suddenly I was curious, as we should always be, when I noticed the Tanakh quote. Where does that come from?
