This is a song of praise for God's spiritual blessings to His people and His kind providence over all the earth. (Psa 65:1-13) Praise waiteth for thee--literally, "To Thee silence praise," or (compare Psa 62:1), To Thee silence is praise--that is, Praise is waiting as a servant; it is due to Thee. So the last clause expresses the duty of paying vows. These two parts of acceptable worship, mentioned in Psa 50:14, are rendered in Zion, where God chiefly displays His mercy and receives homage.
