Exodus 13:6-8

Lexham English Bible

⁶ Seven days you will eat unleavened bread, and on the seventh day will be a feast for Yahweh. ⁷ Unleavened bread will be eaten the seven days; food with yeast will not be seen for you; and yeast will not be seen for you in all your territory. ⁸ And you shall tell your son on that day, saying, ‘This is because of what Yahweh did for me when I came out from Egypt.’
