'Comprehends' in the Bible

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.

You will no longer see a fierce people,A people of unintelligible speech which no one comprehends,Of a stammering tongue which no one understands.

Who comprehends the mind of the Lord, or gives him instruction as his counselor?
