Exodus 13:6-8

Complete Jewish Bible

⁶ For seven days you are to eat matzah, and the seventh day is to be a festival for Adonai. ⁷ Matzah is to be eaten throughout the seven days; neither hametz nor leavening agents are to be seen with you throughout your territory. ⁸ On that day you are to tell your son, ‘It is because of what Adonai did for me when I left Egypt.’
