New song. — See Psalms 33:3. It seems natural to suppose that this new song is incorporated here; that we have at least the substance of it, if not the words. Possibly the very words are taken up in Psalms 40:4. And we are to find the “newness” in the magnificent vindication of spiritual above formal worship.
Shall see it and fear. — Comp. Psalms 52:6, where there is plainly a reminiscence of this passage.
