John Trapp on Nahum 1:2

Verſ. 2. God is jealous] See the Note on Zech. 1.14.

and the Lord revengeth, the Lord revengeth] As he is Pater miſerationum, to his people, a father of mercies, and God of conſolation: ſo to his and their enemies he is a moſt ſure and ſevere revenger, Deus ultionum, as David calleth him, Pſal. 94.1. A God of recompenſes, as Jeremy, chap. 51.56. And when He comes againſt a people, he uſually takes them to do, when they are at the ſtrongeſt, and moſt confident: as Nineveh now was, in the dayes of proud Sennacherib.

and is furious] Heb. and is Maſter of hot wrath: he is all on a light fire, as it were, with fierce indignation againſt the enemies of his Church: Yet not ſo, but that he is Maſter of his anger too; and doth nothing in it, but what is juſt and equall. Hence the vials of his wrath are ſaid to be golden vials, Rev. 15.7. his anger is holy, his fire is pure, and without ſmoak. And this is further declared in the following words.

The Lord will take vengeance on his adverſaries] Such as ſeek to thruſt him beſide his throne, that oppoſe his worſhip, contemn his word, perſecute his people, ſend proud meſſages after him, ſaying. We will not have this man to reigne over us: Bring hither thoſe mine enemies, ſaith He, and ſlay them before me, Luk. 19.27. As for ſuch as ſin of infirmity, and return to him by repentance, they ſhall not find him furious, but gracious.

and he reſerveth wrath for his enemies] Their preſervation for a time, is but a reſervation to that wrath to come. As hee precipitateth not his anger, but defers the execution of it, giving men ſpace to repent, as he did Jezabel, Rev. 2. ſo they ſhall find that his forbearance is no quittance; and that Poena venit gravior, quò magè tarda venit.
