John Trapp on Psalms 149:6

Verſ. 6 Let the high praiſes (or the exaltations) of God bee in their mouth] Heb. In their throat. So Iſa. 58.1. cry aloud; Heb. cry in the throat, ſet up thy note. — Sic clames, ut Stentora vincas.

And a two-edged ſword in their hand] Such an invincible power ſhall the Saints have, as whereby they ſhall ſubdue all their enemies corporall and ſpirituall. See Heb. 14.12. Rev. 1.16. & 19.15. there was more than metall and form in Goliahs ſword, delivered by the Prieſt to David; whoſe arm was not ſo much ſtrengthened by it as his faith: ſo is every good Chriſtians by that two-edged ſword of the Spirit: he may well write upon it as that renouned Talbot in the reign of Henry the ſixth did upon his ſword, Speed. in blunt and boiſterous language, Sum Talbotti (this was ingraven upon the one ſide of the blade, and upon the other) pro vincere inimic[illegible: 1 letter]s [illegible: 1 word]. See a Cor. 10.4, 5.
