And there shall be no leavened bread seen with thee in all thy coast seven days; neither shall there [any thing] of the flesh, which thou sacrificedst the first day at even, remain all night until the morning.
Berean Study Bible (BSB) - Deuteronomy 16:4 >No leaven is to be found in all your land for seven days, and none of the meat you sacrifice in the evening of the first day shall remain until morning.
