John Trapp on Psalms 45:3

All the wars in the conqueſt of Canaan were types of the ſpirituall wars under the Goſpel, whereby the Nations were ſubdued to the obedience of the faith, 2 Cor. 10.4. Epheſ. 6.11. Chriſt hath his ſword then, a two-edged ſword; and he is here called upon to gird it to his thigh (after the manner of thoſe Eaſterlings, as we do our skeans, bangers, woodknives) that is, to take unto him his authority, and to exerciſe it for the converſion of his people, and confuſion of his enemies. Additur [illegible: 1 letter]i gladius quem non oſtentet velut [non-Latin text not transcribed], ſed quem etium deſtring at. A ſword hee hath, not for ſhew, but for ſervice; whence it is added, with thy glory and thy Majeſty. Equita ſuper verbum verit[illegible: 1 letter] tis.
