John Trapp on Isaiah 9:5

Ver. 5. For every battle of the Warriour, &c.] Great is the wo of war; when Death heweth its way through a wood of men, in a minute of time, from the mouth of a murdering piece, when fire and ſword waſte at pleaſure. The birth of Chriſt comforteth againſt all the miſeries of War: whereunto therefore it is oppoſed both here, and Mic. 5.1, 2. See the Note there. Now then as the Iſraelites frighted and flighted the Midianites with ſaying, Hic Gideon, Here's Gideon: ſo may we our ſpiritual enemies, by crying Hic Jeſus: Hoc in ſigno vincemus. Here's Jeſus: we are more then Conquerers through him that loved us.

But this ſhall be with burning] i. e. with the fire of the holy Ghoſt, ſaith Oecolampadius, burning up our corruptions, as chap. 4.4. and moulding us into a new man. Diodate ſenſeth it thus: The world ſhall be filled with blood and wars, and at laſt ſhall be conſumed with fire at the day of Judgement.
