John Trapp on Psalms 27:3

Verſ. 3. Though an Hoſt ſhould encamp againſt me] See Pſal. 3.6. with the Note. We ſhould propound the worſt to our ſelves (the beſt will bring with it, as wee ſay) eſpecially if we finde our faith to be in heart and vigour, as here Davids was.

Though War ſhouldriſe againſt me] War is a complexive evil, and is therefore called ſo by a ſpecialty, Iſa. 45.7. I make peace, and create evil, that is, War; Sin, Satan and War have all one name (ſaith a learned Divine) evil is the beſt of them; the beſt of ſin is deformity, of Satan, enmity, of war, miſery.

In this will I be confident] In this? In what? In this one enſuing Petition, ſaith Aben-Ezra; or, in this that I have ſaid before, The Lord is my light and my Salvation; in this confident gloriation of mine, which is ſuch as an unbeleever is a perfect ſtranger unto.
