Sleep prayers, righteous anger, and God's smile hugs, all covered in this Psalm Short digging into Psalm 4, Answer Me When I Call to the Choir Master with Stringed Instruments, A Psalm of David.

Many of us were taught, implicitly or explicitly, that the key to a peaceful night's sleep is to first fix whatever is wrong. Resolve conflict, remove threat, then rest.

Written by David during a time when he had every reason to sleep with one eye open, this evening psalm closes with one of the remarkably beautiful lines of Scripture: "In peace I will both lie down and sleep, for you alone, O Lord, make me dwell in safety." The Hebrew here is precise. The word for lying down describes an intentional act of surrender. The word for sleep describes full unconscious vulnerability. David isn't describing a situation that has improved. He's describing an internal reorientation that precedes any change in circumstances.

The psalm also contains a surprising permission slip: "Be angry and do not sin." Not suppress or apologize for your anger. We may be angry, agitated, fearful, unsettled. Emotion itself isn't the problem. Paul quotes this exact verse in Ephesians 4, writing to a community about living together without letting anger corrode the bonds between them. Don't let the sun go down on it, he says — which is to say, don't carry it into the night, don't let it become a place you live. Both texts are pointing toward the same thing: the path from distress to peace isn't the elimination of hard feelings, but learning where to take them before you close your eyes.
