Psalm 4:8 is not a sentiment. It’s the conclusion of a theological argument David has been making to himself across the whole psalm — from distress, through trust, to this: In peace I will lie down and sleep. The Hebrew word levadad means you alone, exclusively, no other candidates. Not the locked door. Not the plan. Not the hoped-for outcome. Batach — the safety that comes from leaning full weight and finding it holding. Sleep is where control ends. David slept anyway. Not because the danger had passed, but because he knew who held the night.
