Psalm for Days and Nights

You, O Lord, are a shield around me,
my glory, and the one who lifts up my head.
I cry aloud to the Lord,
and he answers me from his holy hill.
I lie down and sleep;
I wake again, for the Lord sustains me.

I will both lie down and sleep in peace;
for you alone, O Lord, make me lie down in safety.

Psalms 3:3-5; 4:8
