David writes a psalm that begins with David’s dependence on God for his salvation. He then rhetorically asks how long evil men will attack other men. He describes them as leaning walls and tottering fences, that cannot stand against the righteous.
Psalm 62:5–7 (NKJV)
5 My soul, wait silently for God alone,
For my expectation is from Him.
6 He only is my rock and my salvation;
He is my defense;
I shall not be moved.
7 In God is my salvation and my glory;
The rock of my strength,
And my refuge, is in God.
He then goes on to describe men as lighter than vapor, almost insignificant. He encourages men not to depend on riches. He then attributes power and mercy to the Lord, confirming that God renders to each one according to his work.
David wrote this psalm to Jeduthun, an associate. He declares the glory of God and the uselessness of man. He shows, once again, that his faith is in God. David is determined to exalt the Lord and expose the weakness of humanity. In each of his writings, he helps the reader understand the disparity between man and God and then give them hope for a brighter day. He does just that for Jeduthun, and leaves it for us to see as well.
