This compound intensifies 'learn' or 'perceive' with a prefix suggesting thoroughness—to learn by close observation. Matthew 6:28 uses it in Jesus' command to 'consider the lilies of the field,' urging attentive study of how God clothes wildflowers. The aorist imperative calls for deliberate mental focus. Classical usage shows the word for careful inspection, perception, and learning through examination. Spanish 'observad' and French 'considérer' emphasize the intentional, focused nature of this observation. The single biblical occurrence models contemplative attention to creation as antidote to anxiety.
