Daniel 9 [Literal Translation]
24 “Seventy weeks are decreed for your people and your holy city, to restrain (the) transgression, to seal up sins, to make atonement for iniquity, to bring in everlasting righteousness, to seal up vision and prophecy, and to anoint the Most Holy Place.
25 Know therefore and understand: from the issuing of the word to restore and rebuild Jerusalem until the Anointed One, the Prince, there shall be seven weeks and sixty-two weeks. In (the) times of distress, the street and the moat shall be built again.
26 And after the sixty-two weeks, the Anointed One shall be cut off and shall have nothing; and the people of a prince (who) is to come shall destroy the city and the sanctuary. Its end shall come with (the) flood; war shall continue to the end, and desolations are determined.
27 Within one week he shall confirm a covenant with (the) many; and in the midst of the week, he shall bring an end to sacrifice and offering. On the wing of abominations comes one who makes desolate, until the decreed end is poured out on the desolator.”

Daniel 9:27 says: “Within one week he shall confirm a covenant with (the) many.” Who exactly is this “he”? Is it the Lord, or the Antichrist?
There are generally two reasons why people struggle to distinguish whether “he” refers to the Lord Jesus or the Antichrist.
First, the latter half of verse 27 says he will “bring an end to sacrifice and offering,” which easily creates a negative impression. Second, it later speaks of “one who makes desolate,” referring to the Antichrist. Consequently, some interpret the “he” in verse 27 as the Antichrist.
However, looking at the timeline, the first half of the 70th week corresponds to the period of the Lord Jesus’ crucifixion. The “lawless one” (Antichrist) will not be revealed until the three and a half years prior to the Lord’s second coming. Therefore, the “he” here still refers to the Lord.
Verse 27 says he will “confirm” (strengthen/make firm) the covenant. To “confirm” suggests that the covenant already exists, and the Lord Jesus comes to re-establish or strengthen it. What covenant is the Lord Jesus confirming?
And which covenant did the New Covenant confirm?
The covenant the Lord Jesus confirmed is the one made with the house of Israel and the house of Judah. This covenant is the Abrahamic Covenant:
Reading the scriptures in order, “he” naturally refers to the Lord, and “confirming the covenant” is the Lord’s validation of the Abrahamic Covenant.
Thanks and praise be to the Lord!
Note:
Traditionally, some believe this covenant is a seven-year peace treaty signed between the Antichrist and many people, which the Antichrist breaks halfway through (after three and a half years). However, if the analysis of the 70 weeks and the 70th week is correct, this is chronologically impossible. This passage speaks of the first half of the 70th week, whereas the appearance of the Antichrist occurs in the second half of the 70th week.
