Dan 11:31

31 Forces shall stand on his part, and they shall profane the sanctuary, even the fortress, and shall take away the continual [offering], and they shall set up the abomination that makes desolate. 

Arms will come from him –  the armies of angels given over to him (Dan 8:10-12; Rev 12:4).

and shall pollute the sanctuary of strength – he defiles or pollutes the place of Holy Strength. From the expression “pollute the sanctuary of strength,” wə·ḥil·lê·lū ham·miq·dāš ham·mā·‘ō·wz, we know that there is no double meaning here. This does not describe the “destruction” of the Jerusalem temple, but the “pollution” of the truth, as we shall see in verse 32. The corruption of the truth came by the spirit of the antichrist in the Montanists and Tertullian, after 180 AD; these evil spirits were the army of Satan that was cast down to earth and corrupted the truth.

The word for sanctuary, ham·miq·dāš, describes a holy place. The word maoz, is “strength,” “stronghold” or “fortress” and is always, and only, used to describe God Himself, eg 2 Sam 22:33, “God is my strong fortress;” Neh 8:10, “the Lord is your strength;” Psa 27:1, “the Lord is the defense of my life,” etc, etc, etc. The expression maoz never describes the Temple at Jerusalem.

The meaning of “sanctuary of strength” can only refer to the dwelling place of God Himself in the believers, “the Church of God,” “a Holy Temple in the Lord…a dwelling place of God in spirit” (Eph 2:21-22).

and they shall take away the daily sacrifices – more literally “they shall take away the continual offering,” hat·tā·mîḏ, as we discussed in Dan 8:11, this refers to the efficacy of baptism to remit sins, after the spirit of truth was taken from the Church.

and they shall put the abomination of desolation –  the holy place of God was made desolate when the spirit of truth was taken away.
