Midrash sobre Levítico 22:33

6) (Vayikra 22:33) ("Who took you out of the land of Egypt to be your G d; I am the L–rd.") "Who took you out of the land of Egypt": On condition did I take you out of the land of Egypt — that you dedicate yourselves to the sanctification of My name. "to be your G d": (even) against your will. "I am the L–rd" — trusted to reward.
