+Psalm 3Confidence in Troubled Times
+
+1. Lord, how my foes increase!
+There are many who attack me.
+
+2. Many say about me,
+"There is no help for him in God."Selah
+
+3. But you, Lord, are a shield around me,
+my glory, and the one who lifts up my head.
+
+4. I cry aloud to the Lord,
+and he answers me from his holy mountain.Selah
+
+5. I lie down and sleep;
+I wake again because the Lord sustains me.
+
+6. I will not be afraid of thousands of people
+who have taken their stand against me on every side.
+
+7. Rise up, Lord!
+Save me, my God!
+You strike all my enemies on the cheek;
+you break the teeth of the wicked.
+
+8. Salvation belongs to the Lord;
+may your blessing be on your people.Selah
