The final Seventieth Week is to be fulfilled
at the end of the age.

This 'week' of seven years begins when the
prince that shall come or the Antichrist
makes a covenant with the Jews and permits
them to rebuild their temple.

Isaiah tells of this covenant with death,
and how it will be broken in
Isaiah 28:15-18:
"Because ye have said, We have made a
covenant with death, and with hell are we
at agreement; when the overflowing
scourge shall pass through, it shall not
come unto us: for we have made lies our
refuge, and under falsehood have we hid
ourselves:Therefore thus saith the Lord
GOD, Behold,I lay in Zion for a foundation
a stone, a tried stone, a precious corner
stone, a sure foundation: he that believeth
shall not make haste.
Judgment also will I lay to the line, and
righteousness to the plummet: and the hail
shall sweep away the refuge of lies, and the
waters shall overflow the hiding place.
And your covenant with death shall be
disannulled, and your agreement with hell
shall not stand; when the overflowing
scourge shall pass through, then ye shall be
trodden down by it."
