A Psalm of David.
This psalm was probably composed when David assumed the government of his kingdom, and contains his holy resolutions, (1.) To make God’s mercies and judgments the connected matter of his song; and to walk circumspectly before his family, through the assisting presence of God, ver. 1-2. (2.) To purge his family and kingdom; discouraging and punishing persons mischievous, wicked slanderers, liars, and deceitful workers; and encouraging the pious, ver. 3-8.
While I sing, let me remember my faults, and in the strength of the grace that is in Christ Jesus, form the like holy resolutions.
