to panic: to be jolted by sudden fear, and usually to bolt because of it
This is not a neutral word for speed. Hebrew already has plain words for moving fast, מָהַר and חוּשׁ, and they carry no emotion at all. This word names the speed that fear produces. Wherever it turns up, something frightening has just happened and a body is reacting to it.
In most of its nine verses the fear shows up as running:
- a nurse grabs a child and bolts at the news of a royal death (2 Samuel 4:4)
- a besieging army throws away its clothes and gear as it runs (2 Kings 7:15)
- foreign kings look at Jerusalem, see something, and scatter (Psalm 48:5)
- even the waters of creation recoil at God's shout (Psalm 104:7)
In each of those the word stands beside a word for fleeing (נוּס) or for being overwhelmed with dread.
But four verses have no running in them at all, and those are the ones that settle what the word is really about. Soldiers are told not to feel this as they line up for battle (Deuteronomy 20:3). The huge creature of Job 40:23 does not feel it even when a river surges up to his mouth, and he is not moving anywhere; the other half of that line credits him with confidence. And twice a psalmist looks back on a moment of collapse and reports what he said "in my alarm" (Psalm 31:22; Psalm 116:11). So the fear is the heart of the word and the running is simply what fear usually does.
The noun built on the same root (חִפָּזוֹן) shows how much dread the word carries. It is the word for the way Israel ate the first Passover, sandals on and staff in hand on the night Egypt was wailing, and it is the word Isaiah picks up to promise that the journey home from exile will be nothing like that.
