George Haydock's Catholic Commentary
Psalms 85:15
True. This title is also applied to Christ, who, of course, is God:; since every man is liable to mistake, Romans iii. 4., and Apocalypse xix. 1. God authorized Moses and the prophets to address Him, as the psalmist does, Exodus xxxiv. 6., and Joel ii. 13. (Berthier)
