Psalms 149:7

To execute vengeance upon the heathen, [and] punishments upon the people;

Ver. 7. To execute vengeance upon the heathen] viz. Upon a just calling, and not for private revenge; yea, that soldier can never answer it to God that strikes not more as a justicer than as an enemy, be his cause never so good. But that is the most noble vengeance that is executed upon men's lusts; while they thrust the sword of the Spirit into the throats of them, and let out their life blood. That is a good sense that some give of these words, viz. that the saints, when they go forth to battle, should go with holy songs in their mouths, as well as with swords in their hands. See Judges 7:19,20, &c.; 2 Chronicles 20:21, &c.; the victoria Halleluiatica was got on this manner here in Britain, under the conduct of Germanus, against a mighty army of Pelagian Picts and Saxons. Ussier. de Brit. Eccles. Primord. This was the course and custom of the Angrognians in Piedmont against their Popish persecutors; and the like we read of the other French Protestants at the siege of Montaubon; that I mention not those gallant spirits at Edgehill battle with their reboated, Now for the fruit of prayer; together with the many psalms sung by that religious army in their several stations, whereof I have been an ear-witness.
