Exodus 13:8-10

Complete Jewish Bible

⁸ On that day you are to tell your son, ‘It is because of what Adonai did for me when I left Egypt.’

⁹ “Moreover, it will serve you as a sign on your hand and as a reminder between your eyes, so that Adonai’s Torah may be on your lips; because with a strong hand Adonai brought you out of Egypt. ¹⁰ Therefore you are to observe this regulation at its proper time, year after year.
