A corrected end time timeline from the corrected translation of Daniel 9:27

והגביר ברית לרבים שׁבוע אחד וחצי השׁבוע ישׁבית זבח ומנחה ועל כנף שׁקוצים משׁמם ועד־כלה ונחרצה תתך על־שׁמם׃

With proper translation it reads a week and a half and not for one week and in the middle of the week!(שׁבוע אחד וחצי) In the middle of the week in Hebrew is (באמצע השבוע)The scripture clearly says the son of perdition makes a covenant with the "many" the Hebrew word for this(רבים) also meaning leaders or elders. The word for the cover below is (ועל כנף) ve-al kanaph which is the winged cover of the ark of the covenant which normally has the 2 Cheruvim on the cover facing one another toward the mercy seat and using their wings to cover the mercy seat.(Exodus 25:20 And the cherubims shall stretch forth their wings on high, covering the mercy seat with their wings, and their faces shall look one to another; toward the mercy seat shall the faces of the cherubims be. )

So wording the verse more accurately it reads:
Daniel 9:27 And he made a covenant with the leaders for one and a half week, on the seventh day he shall put an end to the sacrifice and the offering and set on the cover the abomination that causes desolation
