to scatter: to drive people or things apart so they spread out over a wide area
This is the common word for breaking a gathered group apart so that its members end up spread across a wide space. It works in both directions: someone (or something) does the scattering, and the people or things scattered get spread abroad. The picture is always a single mass that becomes many separated pieces, whether that is an army melting away from its commander, a crowd dispersing to their tents, seed flung across a field, or arrows shot in every direction.
The word carries its heaviest weight in the prophets, where God is the one who scatters. There it names the central catastrophe of Israel's story: a people pulled out of their land and spread among the nations as judgment. That theological use grows out of the plain physical meaning rather than replacing it, so both belong to one word. The two senses below mark that difference in setting, not a difference in the core idea of forcing a gathered group apart.
The scattering can be a threat, a punishment already carried out, or a thing God promises to reverse by gathering his people back. The same verb that disperses also frames the hope of return, since what was scattered can be brought home again.
