In seven times or years (of 365 days each) are 2555 days. 2555–1290 = 1265. Then the first part of the week is 1265 days long. At the end of the 1290 days the week ends, and the power of the vile person to persecute the saints will be at an end; but not his ruling power over his own subjects. That will continue until the great battle described in Rev. 19:11, when he and his followers will be completely overthrown, and God’s waiting, suffering church rewarded for all their numerous and severe trials.
