Deuteronomy 16:2-4

Living Bible

² Your Passover sacrifice shall be either a lamb or an ox, sacrificed to the Lord your God at his sanctuary. ³ Eat the sacrifice with unleavened bread. Eat unleavened bread for seven days as a reminder of the bread you ate as you escaped from Egypt. This is to remind you that you left Egypt in such a hurry that there was no time for the bread to rise.^[a] Remember that day all the rest of your lives! ⁴ For seven days no trace of yeast shall be in your homes, and none of the Passover lamb shall be left until the next morning.
