Deuteronomy 16:3-4

MSTC(i) 3 Thou shalt eat no leavened bread therewith: but shalt eat therewith the bread of tribulation seven days long. For thou camest out of the land of Egypt in haste, that thou mayest remember the day when thou camest out of the land of Egypt, all days of thy life. 4 And see that there be no leavened bread seen in all thy coasts seven days long, and that there remain nothing of the flesh which thou hast offered the first day at evening, until the morning.
