A high priest that offered the one sacrifice that replaced all of the animal sacrifices.
Then why did Paul make these sacrifices?
(CLV) Ac 21:26
Then Paul, taking the men along on the next day, being purified together with them, had been in the sanctuary, publishing the full completion of the days of purification, till w the approach present for each one of them was offered.
Why does Ezekiel speak of sacrifices of the Millennial Reign?
Ezekiel 43:
19 And you have given unto the priests, the Levites, who [are] of the seed of Zadok--who are near unto Me, an affirmation of the Lord Yahweh, to serve Me--a calf from the herd, for a sin-offering." 20 And you have taken of its blood, and have put it on its four horns, and on the four corners of its border, and on the border round about, and have cleansed it, and purified it." 21 And you have taken the bullock of the sin-offering, and have burnt it in the appointed place of the house at the outside of the sanctuary." 22 And on the second day you do bring near a kid of the goats, a perfect one, for a sin-offering, and they have cleansed the altar, as they cleansed [it] for the bullock." 23 In your finishing cleansing, you do bring near a calf, a son of the herd, a perfect one, and a ram out of the flock, a perfect one." 24 And you have brought them near before Yahweh, and the priests have cast upon them salt, and have caused them to go up, a burnt-offering to Yahweh." 25 Seven days you do prepare a goat for a sin-offering daily, and a bullock, a son of the herd, and a ram out of the flock, perfect ones, do they prepare." 26 Seven days they purify the altar, and have cleansed it, and filled their hand." 27 And the days are completed, and it has come to pass on the eighth day, and henceforth, the priests prepare on the altar your burnt-offerings and your peace-offerings, and I have accepted you--an affirmation of the Lord Yahweh.'"
....and how would you explain this?:
(CLV) Jer 33:20
Thus says Yahweh: If you could annul My covenant with the day and My covenant with the night so that daytime and night fail to come about in their proper time,
(CLV) Jer 33:21
then also My covenant could be annulled with
David My servant, so that he should not come to have
a son reigning on his throne, and that with the Levites, the priests, My ministers.
