John Trapp on Amos 1:2

Verſe 2. And he ſaid, The Lord will roar,] This is ſpoken for the terrour of the wicked, as the like was Ioel 3.16. for the comfort of the godly. See the Note there. The word, as Moſes, ſaves the Iſraelite, ſlayes the Egyptian; and is, as the fragrancy of precious ointment: of which Oecumenius tells us,Columbam vegetat, ſcarabaeum necat. Oecum. that it refreſheth the Dove, but killeth the Beetle. See 2 Cor. 2.16. with the Note. The Prophet here tells Idolatrous Iſrael to their teeth, that God will no longer deal fairly with them as a ſhepherd, but fiercely as a lion: he will not onely roar upon them, but rent the caul of their hearts: as the lion, together with his roar, layes his pawes upon the prey. And that ye may know that theſe are not bug-bear termes, deviſed on purpoſe to affright ſilly people, and that I ſhoot not Fot-guns at you.

the habitations of the ſhepherds ſhall mourn, &c.] That is, all your bravery ſhall down: all your wealth and wordly greatneſſe ſhall wither: the top of your Carmel, the Zenith of your proſperity ſhall be blaſted, and the ſcene ſoon altered. All this the Prophet uſed to ſhepherdy,Navita de ventis, de tauris narrat orator. Bucholcer. expreſſeth accordingly, Artis ſuae uſus ſermonibus (as it is naturall for all Artiſts to do) but with a great deal of life and boldneſſe. Verbis vivis, animatis ſententiis, & ſpiritus fervore flagrantiſſimus, as One ſaith of Savanarolas Meditations upon Pſal. 51.
