Be Careful to Do Everything I Have Said to You
23: 13

This verse is the climax of the Book of the Covenant. Be careful to do everything I have said to you on Mount Sinai. Do not invoke the names of other gods; do not let them be heard on your lips. The rabbis taught that the sin of idolatry violated all the commandments of the Torah. They taught that it was sinful to even form partnerships with idolaters for fear that they would swear by His name, and the Israelite be held responsible for what the idolater said. The Book of the Covenant started out with this command: Do not make any gods to be alongside Me; do not make for yourselves gods of silver or gods of gold (20:23), now it returns to it. Monotheism was the first commandment, and it marked the beginning and the end of the Book of the Covenant. Therefore, it bound it together. It is the main doctrine of Jewish theology in the Torah both during the days of Moses and today.
