O give thanks unto the LORD; for [he is] good: for his mercy [endureth] for ever.
Ver. 1. O give thanks unto the Lord] This psalm is by the Jews called Hillel gadol, the great gratulatory. See Psalms 106:1; Psalms 107:1; Psalms 118:1 .
For his mercy endureth for ever] His covenant mercy, that precious Church privilege; this is perpetual to his people, and should perpetually shine as a picture in our hearts. For which purpose this psalm was appointed to be daily sung in the old church, by the Levites, 1 Chronicles 16:41 .
