Seven days shalt thou prepare every day a goat for a
sin offering
By this it appears that the altar was seven days a consecrating and cleansing; and that on each day a goat was prepared and offered, typical of Christ, as before observed. Here Kimchi owns that this was not according to the order of Moses, or was done by those that came out of the captivity of Babylon; and is obliged to confess that there will be a change or an innovation in the order of sacrifices in time to come, or under the Messiah. They shall also prepare a young bullock, and a ram out of the flock
without blemish;
which, either one or all of them, should be offered up on each of the seven days; (See Gill on Ezekiel 43:23).
