Damam (H1826) means to be silent, to be still, to cease — used of the cessation of sound, movement, or life. It ranges from the silence of waiting (Psalm 37:7) to the silence of death (Psalm 31:17) to the commanded stillness before God.
Psalm 37:7 commands: 'Be still (dom) before the LORD and wait patiently for him.' The root of this command is not passivity but trust — the quiet confidence of one whose expectations rest entirely in God. The related concept appears in 'Be still and know that I am God' (Psalm 46:10, though that uses raphah). Silence before God is posture of reverence and faith.
