2 Chronicles 35:17

Seven days shall ye eat unleavened bread; even the first day ye shall put away leaven out of your houses: for whosoever eateth leavened bread from the first day until the seventh day, that soul shall be cut off from Israel. And in the first day there shall be an holy convocation, and in the seventh day there shall be an holy convocation to you; no manner of work shall be done in them, save that which every man must eat, that only may be done of you. And ye shall observe the feast of unleavened bread; for in this selfsame day have I brought your armies out of the land of Egypt: therefore shall ye observe this day in your generations by an ordinance for ever. In the first month, on the fourteenth day of the month at even, ye shall eat unleavened bread, until the one and twentieth day of the month at even. Seven days shall there be no leaven found in your houses: for whosoever eateth that which is leavened, even that soul shall be cut off from the congregation of Israel, whether he be a stranger, or born in the land. Ye shall eat nothing leavened; in all your habitations shall ye eat unleavened bread.

Seven days thou shalt eat unleavened bread, and in the seventh day shall be a feast to the LORD.

Thou shalt keep the feast of unleavened bread: (thou shalt eat unleavened bread seven days, as I commanded thee, in the time appointed of the month Abib; for in it thou camest out from Egypt: and none shall appear before me empty:)

The feast of unleavened bread shalt thou keep. Seven days thou shalt eat unleavened bread, as I commanded thee, in the time of the month Abib: for in the month Abib thou camest out from Egypt.

In the fourteenth day of the first month at even is the LORD's passover. And on the fifteenth day of the same month is the feast of unleavened bread unto the LORD: seven days ye must eat unleavened bread. In the first day ye shall have an holy convocation: ye shall do no servile work therein. But ye shall offer an offering made by fire unto the LORD seven days: in the seventh day is an holy convocation: ye shall do no servile work therein.

And in the fourteenth day of the first month is the passover of the LORD. And in the fifteenth day of this month is the feast: seven days shall unleavened bread be eaten. In the first day shall be an holy convocation; ye shall do no manner of servile work therein: But ye shall offer a sacrifice made by fire for a burnt offering unto the LORD; two young bullocks, and one ram, and seven lambs of the first year: they shall be unto you without blemish: And their meat offering shall be of flour mingled with oil: three tenth deals shall ye offer for a bullock, and two tenth deals for a ram; A several tenth deal shalt thou offer for every lamb, throughout the seven lambs: And one goat for a sin offering, to make an atonement for you. Ye shall offer these beside the burnt offering in the morning, which is for a continual burnt offering. After this manner ye shall offer daily, throughout the seven days, the meat of the sacrifice made by fire, of a sweet savor unto the LORD: it shall be offered beside the continual burnt offering, and his drink offering. And on the seventh day ye shall have an holy convocation; ye shall do no servile work.

And the children of Israel that were present at Jerusalem kept the feast of unleavened bread seven days with great gladness: and the Levites and the priests praised the LORD day by day, singing with loud instruments unto the LORD. And Hezekiah spake comfortably unto all the Levites that taught the good knowledge of the LORD: and they did eat throughout the feast seven days, offering peace offerings, and making confession to the LORD God of their fathers. And the whole assembly took counsel to keep other seven days: and they kept other seven days with gladness.
