Verb anatheōreō (to examine carefully) in the Gospels-Acts

(Translation from NRSV with a few modifications for a more literal meaning)

Acts

17: 23For as I went through the city and examining carefully (anatheōreō) at the objects of your worship, I found among them an altar with the inscription, 'To an unknown god.' What therefore you worship as unknown, this I proclaim to you.
