O come, let us sing unto the LORD: let us make a joyful noise to the rock of our salvation.
Ver. 1. O come, let us sing unto the Lord] It is thought by this beginning that this psalm was not penned by David for private use, but for public assemblies, to be sung by the congregation on the sabbath and such like times. It may very well be that they began their morning sacrifice with this psalm, as the Latin Church also afterwards did their matins, or morning service.
Let us make a joyful noise] With a clear and loud voice, as of a trumpet; singing with grace in our hearts unto the Lord.
