+Psalm 123Looking for God's Favor
+
+1. I lift my eyes to you,
+the one enthroned in heaven.
+
+2. Like a servant's eyes on his master's hand,
+like a servant girl's eyes on her mistress's hand,
+so our eyes are on the Lord our God
+until he shows us favor.
+
+3. Show us favor, Lord, show us favor,
+for we've had more than enough contempt.
+
+4. We've had more than enough
+scorn from the arrogant
+and contempt from the proud.
