The Book of Vayikrah concludes with Moshe contrasting the different responses that will follow the Jews’ obedience or defiance of Hashem’s commandments. Obedience will lead to peace and prosperity; abundant crops; and protection from our enemies. Defiance will lead to (among other things, and in stages of increasing severity): plagues; enemy sieges; and national exile. However, if the Jews repent, Hashem promises to once again remember His covenant with the Patriarchs and accept us once again as His people.
