Psalm 123 - Look to God For Mercy

The author of Psalm 123 is not known; however some think it could of been Hezekiah.  Hezekiah’s life is, for the most part, a model of faithfulness and trust in the Lord. His faith was more than superficial, as his bold reforms show. Hezekiah’s trust in the Lord was rewarded with answered prayer, successful endeavors, and miraculous victory over his enemies. When faced with an impossible situation, surrounded by the dreadful and determined Assyrian army, Hezekiah did exactly the right thing—he prayed. And God answered.

Psalm 123:1 - "I lift up my eyes to you, to you whose throne is in heaven"

The psalmist, whether it was Hezekiah or not, lifted their eyes to God, waiting and watching for God to send his mercy.  The more he waited, the  more he cried out to God because he knew that the evil and proud offered no help - they had only contempt for God.

Psalm 123 / New International Version

¹ I lift up my eyes to you,
    to you whose throne is in heaven.
² As the eyes of slaves look to the hand of their master,
    as the eyes of a maid look to the hand of her mistress,
so our eyes look to the Lord our God,
    till he shows us his mercy.

³ Have mercy on us, O Lord, have mercy on us,
    for we have endured much contempt.
⁴ We have endured much ridicule from the proud, 
    much contempt from the arrogant.
