John Trapp on Psalms 13:4

Verſ. 4. Leſt mine enemy ſay, I have prevailed againſt him] This David frequently deprecateth, as a great evill, becauſe Gods honour was concerned in it, and would ſuffer by it. As unskilfull hunters ſhooting at wild Beaſts, do ſometimes kill a man; ſo Perſecutors ſhooting at Saints, hit Chriſt, reproach him; and this the Saints are very ſenſible of.

And thoſe that trouble me rejoyce when I am moved] Compoſe Comedies out of my Tragedies, & iram Dei ad calumniam rapiant. The wicked are vindictive and implacable, ſick of the Devills diſeaſe [non-Latin text not transcribed], rejoycing at other mens harms, revelling in other mens ruins; But this is to inrage God, and haſten wrath, Prov. 24.17, 18.
