Charles H. Spurgeon on Psalms 9:3

"When mine enemies are turned back," etc. Were turned back, repulsed, and put to flight. To render this in the present time, as our translators did, is certainly improper; it destroys the coherence, and introduces obscurity. Ainsworth saw this, and rendered in the past, "When mine enemies turned backward." "At thy presence." That is, by thine anger. For as God's presence or face denotes his favour to such as fear and serve him, so it denotes his anger towards the wicked. "The face of Jehovah is against them that do evil." B. Boothroyd, 1824.
