The 70th week in the book of Daniel-

DANIEL 9:24-27- SEVENTY WEEKS ARE DECREED ABOUT YOUR PEOPLE AND YOUR HOLY CITY, TO FINISH THE TRANSGRESSION, TO PUT AN END TO SIN, AND TO ATONE FOR INIQUITY, TO BRING IN EVERLASTING RIGHTEOUSNESS, TO SEAL BOTH VISION AND PROPHET, AND TO ANOINT THE MOST HOLY PLACE.  KNOW THEREFORE AND UNDERSTAND THAT FROM THE GOING OUT OF THE WORD TO RESTORE AND BUILD JERUSALEM TO THE COMING OF AN ANOINTED ONE, A PRINCE, THERE SHALL BE SEVEN WEEKS.  THEN FOR SIXTY TWO WEEKS IT SHALL BE BUILT AGAIN WITH SQUARES AND MOAT, BUT IN A TROUBLED TIME.  AND AFTER THE SIXTY-TWO WEEKS, AN ANOINTED ONE SHALL BE CUT OFF AND SHALL HAVE NOTHING.  AND THE PEOPLE OF THE PRINCE WHO IS TO COME SHALL DESTROY THE CITY AND THE SANCTUARY.  ITS END SHALL COME WITH A FLOOD, AND TO THE END THERE SHALL BE WAR.  DESOLATIONS ARE DECREED.  AND HE SHALL MAKE A STRONG COVENANT WITH MANY FOR ON WEEK, AND FOR HALF OF THE WEEK HE SHALL PUT AN END TO SACRIFICE AND OFFERING.  AND ON THE WING OF ABOMINATIONS SHALL COME ONE WHO MAKES DESOLATE, UNTIL THE DECREED END IS POURED OUT ON THE DESOLATOR.  

DANIEL 12:1- AT THAT TIME SHALL ARISE MICHAEL, THE GREAT PRINCE WHO HAS CHARGE OF YOUR PEOPLE.  AND THERE SHALL BE A TIME OF TROUBLE, SUCH AS NEVER HAS BEEN SINCE THERE WAS A NATION TILL THAT TIME, BUT AT THAT TIME YOUR PEOPLE SHALL BE DELIVERED, EVERYONE WHOSE NAME SHALL BE FOUND WRITTEN IN THE BOOK.  

The tribulation is the seventy week as prophesied in the book of Daniel.
