Now I am come to make thee understand what shall befall thy people in the latter days: for yet the vision is for many days.
I am come to make thee understand what shall befall thy people in the latter days - an intimation that the prophecy, besides describing the doings of Antiochus, reaches to the concluding calamities of Israel's history, prior to the nation's full restoration at Christ's second coming-calamities of which Antiochus' persecutions were the type.
For yet the vision is for many days - i:e., extends far into the future.
