'Investigation' in the Bible

Pursuant to my edict, an investigation has been undertaken. It is noted that this city has fomented rebellion against kings from time immemorial, and that rebellion and sedition has occurred in it.

By the first day of the first month they concluded their investigation of all of the men who had married foreign wives.

So after thinking it over carefully, I accused the officials and nobles openly, "Every one of you is charging your fellow countrymen interest!" So I opened a public investigation against them.
