'Comprehend' in the Bible

God thunders marvelously with his voice. He does great things, which we can't comprehend.

then I saw all the work of God, that man can't find out the work that is done under the sun, because however much a man labors to seek it out, yet he won't find it. Yes even though a wise man thinks he can comprehend it, he won't be able to find it.

You will no longer see the fierce people, a people of a deep speech that you can't comprehend, with a strange language that you can't understand.
