Charles H. Spurgeon on Psalms 96:1

A new song. It must be "a new canticle, "a beautiful canticle, and elegantly composed; also a canticle for fresh favours: in like manner, a canticle befitting men who have been regenerated, in whom avarice has been supplanted by charity; and finally, a canticle not like that of Moses, or Deborah, or any of the old canticles that could not be sung outside the land of promise, according to Ps 137:4; "How shall we sing the LORD'S song in a strange land?" but a new canticle that may be sung all over the world; and he, therefore, adds, Sing unto the LORD, all the earth, not only Judea, but the whole world.
