Dan 9:27

27 He shall make a firm covenant with many for one seven: and after half a seven he shall cause the sacrifice and the offering to cease; and on the wing of abominations [shall come] one who makes desolate; and even to the full end, and that determined, shall [wrath] be poured out on the desolator.

He will confirm a covenant with many for one seven – this seven is divided into two halves. After the first “half of a seven,” Satan, “the Prince of the Covenant” crucified Christ. The second half of a seven, or 3 1/2 years, describes the times, times and half a time, when the saints were given into the hand of the little horn.  

after have a seven he will put an end to sacrifice and offering – the Messiah began His mission, in A.D. 27, after the 7 and 62 sevens described in verse 25. Then after half a seven, He was crucified, and put an end to the daily offerings, and the sacrifice. The word used here is not “tamid” as in Dan 8,11, and 12. Rather, the word used in Dan 9:27, is “zebah uminhah” and refers to the normal grain offering, which ceased for the saints, when the New Covenant was established.

Jesus was cut off after 3 1/2 years. That is after “time, times and half a time.” It is generally accepted that Jesus was baptized in the fall of A.D. 27. This was the fifteenth year of Tiberius, as recorded in Luke 3:1. Adding 69 sevens to the year 457 B.C., we come to the fall of A.D. 27, when Christ was anointed in His baptism. According to Luke 3:1, this was in the 15th year of the reign of Emperor Tiberius.  Tiberius was granted authority to govern the provinces soon after his military celebration on October 23, A.D. 12. (Augustus 97:1; Tiberius 20–21; From the Fasti Praenestini inscription, on October 23, A.D. 12 “Tiberius rode a chariot in triumph from Illyricum.”)

The Apostle John described two Passovers and an unnamed feast in the first six Chapters of his Gospel. We know the unnamed feast in John 5:1 was the Passover, because in John 4:35, Jesus said, “you say there are four months and then comes the harvest.” The Passover was the next feast.

The Passover in A.D. 31 fell on a Wednesday according to the moon record of the US Navy Observatory. According to Exod 12:6, and Lev 23:5, the Passover should be held on the 14th Day of Nissan. However, this date is affected by the rules of the Rabbis. The Passover (Pesach) can only be held on Saturday, Sunday, Tuesday, or Thursday. This can be verified on the schedule for the years 2000 – 2050. For example, in the year 2000, 2002, and 2003, the Passover was on Thursday, the 15th of Nissan. A Thursday Passover agrees with Luke 24:21, and the Second Century Gospel of Peter, discovered in 1886.

In the year A.D. 31, they moved the Passover to Thursday, the 15th Day of Nissan. This fulfilled the word of the Targum of Hos 3:2 which said, “I redeemed them by My Memra (My Word) on the fifteenth day of the month of Nisan.” 

In fact, A.D. 31, is the only possibility, as we can see from the dates calculated by the US Navy Observatory.

on the wing of abominations [shall come] one who makes desolate – the expression “wing” describes the pinnacle of the temple, this is the Greek word πτερύγιον that we find in Matt 4:5. Satan stands on the pinnacle of abominations, in “Mystery Babylon the Great.”

until the end that is decreed is poured out on him – that is the end of Satan’s work through the Beast described in Dan 7:26, “they shall take away his dominion.” This end of the Beast was prefigured in the King of Babylon in Dan 5:26, “God has numbered your kingdom and finished it.”
