Bo: Chapter 10
Matzah of Judgment

Rabbi Shimon talks about the time that the moon was in a decreased state, when Yisrael had not yet completed the Covenant by the uncovering of the corona. After they were uncovered, God gave them bread from a higher place, from the heavens. Then Yisrael observe those days when they entered under the wings of the Shechinah and guarded the bread, the Matzot, that came from its side.

The bonds which Rabbi Shimon refers to next are those that join the upper to the lower levels, and in the observance of the sacrifice those bonds are strengthened, as when the lamb is sacrificed.
