'Searched' in the Bible

“Behold this; we have investigated it, and it is true.Hear and heed it, and know for yourself [for your own good].”

“Inquire, please, of past generations,And consider and apply yourself to the things searched out by their fathers.

Then He saw wisdom and declared it;He established it and searched it out.

“I was a father to the needy;I investigated the case I did not know [and assured justice].

“You see, I waited for your words,I listened to your [wise] reasons,While you pondered and searched out what to say.
