Exodus 13:1-3 New King James Version (NKJV)

1. Then the Lord spoke to Moses, saying,

2. “Consecrate to Me all the firstborn, whatever opens the womb among the children of Israel, both of man and beast; it is Mine.”

3. And Moses said to the people: “Remember this day in which you went out of Egypt, out of the house of bondage; for by strength of hand the Lord brought you out of this place. No leavened bread shall be eaten.
