1 The Lord spoke to Moses in the Sinai desert in the first month of the second year after they had left the land of Egypt:
2 Let the Israelites keep the Passover at its appointed time.
3 On the fourteenth day of this month at twilight you will keep it at its appointed time. Keep it according to all its regulations and its customary practices.
4 Moses instructed the Israelites to keep the Passover.
