'Searched' in the Bible

Put the question now to the past generations, and give attention to what has been searched out by their fathers:

Who does great things not to be searched out; yes, wonders without number.

Will it be good for you to be searched out by him, or have you the thought that he may be guided into error like a man?

Truly, God is great, greater than all our knowledge; the number of his years may not be searched out.

He does wonders, more than may be searched out; great things of which we have no knowledge;

Who is this who makes dark the purpose of God by words without knowledge? For I have been talking without knowledge about wonders not to be searched out.
