Katanoeo denotes attentive noticing or considering, whether examining what is seen or weighing a person or situation.

The verb most often marks attentive observation of something visible or immediately present: animals, a shoreline, a striking sight, a face in a mirror, ravens, lilies, or one’s own fault. It also appears for deliberate consideration of Jesus, mutual encouragement, and bodily circumstances, and once for perceiving opponents’ craftiness.

1. Attentively examining or noticing · dominant

   In Acts 11:6 the imperfect form occurs as the speaker looks into a vessel and observes its animals; Acts 27:39 similarly places the imperfect form with noticing a bay. Imperative forms in Luke 12:24 and Luke 12:27 direct attention to ravens and lilies, while James 1:23 and James 1:24 use present participial and aorist indicative forms in the mirror comparison, where the man observes himself and then forgets.

2. Deliberately considering a person or circumstance · common

   Hebrews 3:1 uses an aorist active plural form in the exhortation to consider Jesus, and Hebrews 10:24 uses a present active subjunctive plural form for considering how to stir one another toward love and good works. In Romans 4:19, the aorist form occurs with considering his own body and Sarah’s womb.

3. Perceiving what is concealed in conduct · rare

   In Luke 20:23, the aorist active participle introduces the response after their craftiness is perceived. The clause supports recognition of their intent rather than merely looking at an object.

   Luke 20:23

In the Anselm Project Bible: The APB variously presents the clauses with “observed,” “noticed,” “examine,” “consider,” and “perceiving.” Because its English is a whole-verse translation, these renderings show the surrounding clauses rather than establishing separate English equivalents for every occurrence.
