“In this Torah portion, Moses details many of God’s laws to the Israelites. These
include laws about worshiping other gods, kashrut, business ethics and treatment of
animals. God outlines the details of three holidays: Passover, Shavuot and Sukkot.
God provides an angel to protect the Israelites from their enemies and warns the
Israelites not to worship other gods. Moses ascends Mount Sinai to meet with God
for 40 days and 40 nights, leaving Aaron and Hur in charge.” (from
