to see, in the heightened sense of perceiving something with full attention: to behold, gaze upon, or receive a vision
This verb means to see, but it carries more weight than simply having one's eyes open. Where the everyday Hebrew word for seeing covers any kind of looking, this one tends to mark seeing that is charged: a prophet receiving a vision from God, a worshiper gazing intently on God or his works, or a wise person looking hard enough to draw a lesson from what they observe.
Its most distinctive home is prophecy. The opening lines of Isaiah, Amos, Micah, and Habakkuk all use this verb for what the prophet saw, and the noun built from it is the standard word for a prophetic vision and for the seer who receives it. When Ezekiel attacks the false prophets, he keeps using this same verb against them: they claim to see, but what they see is empty.
The other senses grow naturally out of this core of attentive seeing. To gaze on God's beauty in the temple, to behold his mighty acts, or to look closely at a person at work are all the same act of fixing one's sight on something and taking it in fully. Many of the word's occurrences sit in poetry, especially in Job and the Psalms, where it lends a note of contemplation that plain seeing would not.
