The church, indeed every Christian, is an odd combination of self-sacrificing saint and self-serving sinner. And the church, unlike some social organizations, doesn't have the luxury of choosing its members; the church is an assembly of all who professed themselves believers (Marshall Shelly).

EXPOSITION.

God’s presence is evermore sufficient to work the defeat of our most furious foes, and their ruin is so complete when the Lord takes them in hand, that even flight cannot save them, they fall to rise no more when he pursues them. We must be careful, like David, to give all the glory to him whose presence gives the victory. If we have here the exultings of our conquering Captain, let us make the triumphs of the Redeemer the triumphs of the redeemed, and rejoice with him at the total discomfiture of all his foes.

EXPLANATORY NOTES AND QUAINT SAYINGS.

Verse 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.

Verse 3.–“_They shall fall and perish_.” It refers to those that either faint in a march, or are wounded in a battle, or especially that in flight meet with galling haps in their way, and so are galled and lamed, rendered unable to go forward, and so fall, and become liable to all the chances of pursuits, and as here, are overtaken and perish in the fall.–^Henry Hammond, D.D.
