John Trapp on Psalms 48:7

Verſ. 7. Thou breakeſt the ſhips of Tarſhiſh] i. e. Of the Ocean, or of the Mediterranean Sea, Iſa. 2.16. & 23.1, 6, 10, 14. The meaning is, like as thou O God with thine Eaſt-wind that Euroclydon eſpecially, which Pliny calleth Navigantium Peſtem (the Mariners miſchief) art wont to daſh and drown the talleſt ſhips at thy pleaſure; ſo thou both canſt, and wilt deal by thy Churches enemies: To whom therefore this Text ſhould be as thoſe knuckles of a mans hand were to Belſhazzer, to write them their deſtiny; or as Daniel was to him, to read it unto them.
