'Comprehend' in the Bible

I have examined all this by wisdom; I said, "I am determined to comprehend this" -- but it was beyond my grasp.

I tried to understand, examine, and comprehend the role of wisdom in the scheme of things, and to understand the stupidity of wickedness and the insanity of folly.

then I discerned all that God has done: No one really comprehends what happens on earth. Despite all human efforts to discover it, no one can ever grasp it. Even if a wise person claimed that he understood, he would not really comprehend it.
