I see. Strange way of saying “time, times, half a time” instead of simply saying “three and a half year”.
It’s important to realize the genre of this passage: it’s called
apocalyptic, and it’s meant to provide hope to those who are in distress. It’s not quite a
prophecy, per se, but it shares some elements in common with prophecy.
One of the things that apocalyptic literature does is use ambiguity as a means to conceal exact times at which the predictions might come true. It’s ambiguous because
it’s not attempting to give you a prophecy that you can write down in your calendar. (By the way, you’ll find this phrase used in Daniel 7, as well). One way to interpret this is by noticing that it’s 3 1/2 units of time. For Jews, if the number seven represented ‘perfection’, guess what half of that represents?
Imperfection (or, as it were wickedness).
But, look at the passage in its context: the man in linen is asked to let Daniel know when these things will happen. Daniel himself says, “umm… I don’t get it.” In a way, the passage is telling us, “keep the faith! you won’t know the day or the hour, but God’s goodness will prevail!”
