In this short but important work, McClain introduces the first 69 weeks and answers questions such as "What is the measure of time indicated by the 'weeks' of this prophecy?" and "When did the whole period of the seventy weeks begin?" Continuing with a discussion of the parenthesis of time between the 69th and the 70th weeks, he concludes with an exposition of the 70th week and the coming of the Roman Prince.
