Charles H. Spurgeon on Psalms 149:1

Whole Psalm. The foregoing Psalm was a hymn of praise to the Creator; this is a hymn to the Redeemer. —Matthew Henry.

Whole Psalm. The New Testament spiritual church cannot pray as the Old Testament national church here prays. Under the illusion that it must be used as a prayer without any spiritual transmutation, Ps 149:1-9 has become the watchword of the most horrible errors. It was by means of this Psalm that Caspar Scloppius, in his Classicum Belli Sacri, which, as Bakius says, is written, not with ink, but with blood, inflamed the Roman Catholic princes to the Thirty Years' Religious War. And in the Protestant church Thomas Muntzer stirred up the War of the Peasants by means of this Psalm. We see that the Christian cannot make such a Psalm directly his own, without disavowing the apostolic warning, "The weapons of our warfare are not carnal" (2Co 10:4). The praying Christian must therefore transpose the letter of this Psalm into the spirit of the New Covenant. —Franz Delitzsch.

A new song; for this Psalm is a song of renovation. If Israel when restored and renewed had new cause for rejoicing, much more should the New Covenant Israel feel constrained to strike the new note of triumph. Infidels blaspheme, the ungrateful murmur, the thoughtless are silent, the mournful weep, all acting according to their old nature; but new men take up a new mode, which is the divinely inspired song of peace, charity, and joy in the Lord. —Johannes Paulus Palanterius.
