So? The 14th is a different day than the 15th, and so on...
Liturgically yes. The days of unleavened bread are evening to evening. The feast days liturgically concern their sacrifices, are morning by morning. Each day has it's sacrifice for the feast days. Besides, What I copied and pasted was how Jew's did it.
Daily two sacrifices, one in the morning, and one in the evening.......Liturgical....
Nu 28:4 The one lamb shalt thou offer in the morning, and the other lamb shalt thou offer at even;
Nu 28:8 And the other lamb shalt thou offer at even: as the meat offering of the morning, and as the drink offering thereof, thou shalt offer it, a sacrifice made by fire, of a sweet savour unto the LORD.
See here.........
17 And in the fifteenth day of this month is the feast: seven days shall unleavened bread be eaten.
18 In the first day shall be an holy convocation; ye shall do no manner of servile work therein:
19 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:
20 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;
21 A several tenth deal shalt thou offer for every lamb, throughout the seven lambs:
22
And one goat for a sin offering, to make an atonement for you.
23
Ye shall offer these beside the burnt offering in the morning, which is for a continual burnt offering.
24 After this manner ye shall offer daily, throughout the seven days, the meat of the sacrifice made by fire, of a sweet savour unto the LORD: it shall be offered beside the continual burnt offering, and his drink offering.
I emphasized vs 22 because Josephus records that these goats for sin were added specifically as a feast for the priests. As only they could eat a sin offering.
I am not sure if you are familiar with Alfred Edersheim, but he has written several book on the temple and Judaism. He says, he cannot understand how the church could not miss this sacrifice as a feast for the priests in Joh 18:28.
Then led they Jesus from Caiaphas unto the hall of judgment: and it was early; and they themselves went not into the judgment hall, lest they should be defiled; but that they might eat the passover.
They were to leave none of the sacrifices till the fowing morning. These days each had a sacrifice of their own.
