Ezekiel 45:21-23

In the first month, in the fourteenth day of the month, ye shall have the passover, a feast of seven days; unleavened bread shall be eaten. In the first month, in the fourteenth day ... ye shall have the Passover ... And seven days of the feast he shall prepare a burnt offering to the Lord, seven bullocks and seven rams without blemish daily. As a new solemnity, the feast of consecration is to prepare for the Passover, so the Passover itself is to have different sacrifices from those of the Mosaic law. Instead of one ram and seven lambs for the daily burnt offering, there are to be seven bullocks and seven rams.
