Exodus 13:8-10

New Century Version

⁸ On that day you should tell your son: ‘We are having this feast because of what the Lord did for me when I came out of Egypt.’ ⁹ This feast will help you remember, like a mark on your hand or a reminder on your forehead. This feast will remind you to speak the Lord’s teachings, because the Lord used his great power to bring you out of Egypt. ¹⁰ So celebrate this feast every year at the right time.
