Exodus 13:8-9
Exodus 13:8-9 NCV
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.’ 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.
