θεωρέω
theōréō · verb · “to see, behold”
Theōreō means to look at attentively, gaze, behold. Distinct from a casual glance, it is steady, perceptive seeing — often used of the disciples watching Jesus.
Theōreō (the root of «theory») describes attentive looking. The disciples theōreō Jesus walking on water, the crowds theōreō his crucifixion, Mary theōreō two angels in the tomb.
John uses the word for a faith that perceives Jesus rightly — «whoever sees (theōreō) me sees him who sent me» (John 12:45). To behold rightly is part of believing.
Definition: to be a spectator of, i.e. discern, (literally, figuratively (experience) or intensively (acknowledge))
KJV usage: behold, consider, look on, perceive, see
