Vayikra: Chapter 30
"Nor have we been false to Your covenant"

We read here of the importance of the Holy Covenant of circumcision. The Torah is also called a covenant. Rabbi Shimon says that the two Sfirot of Judgment and Mercy join together and are the openings to all the other Sfirot; the covenant is attached to them day and night. We hear about the difference between the children of Yisrael and the heathen nations.
