And the people stood afar off, and Moses drew near unto the thick darkness where God was.

Exodus 20:21

This verb means “to stand” but can be used in a wide variety of applications, such as to be erect or upright, to remain or maintain in the sense of standing in one place or to establish or appoint in the sense of being stood in a position. The noun form, amud (Strongs #5982), is a pillar which stands firm and tall. Both the verb and noun form can be found in Exodus 14:19: and the pillar (amud) of the cloud went from before their face, and stood (amad) behind them.
