The design of this psalm is to reprove the common miscarriages of many professors of religion, who satisfied their own consciences, and fancied that they pleased God with their external and ceremonial performances, notwithstanding their neglect of piety, justice, and charity: and to instruct men concerning the nature of the true and acceptable worship of God. The glorious appearance of the great judge, ver. 1-6. Instructions given how to worship him, ver. 7-15. A reproof of those who pretend to worship him, while they disobey his commands, ver. 16-20. Their doom read, and warning given to all, to order their conversation aright, ver. 21-23. A psalm of Asaph. Title of the psalm. Asaph - Who was not only the chief of the sacred singers, but also a prophet, 2 Chron. xxix, 30, and a composer of several psalms, 2 Chron. xxix, 30.
