Many say of me, “God will not deliver him.” Selah

PSALM 3. David, although driven from his kingdom, and pressed down with utter despair of relief from every earthly quarter, ceases not to call upon God, and supports himself from his promise against the greatest terrors, against the mockery and cruel assaults of his enemies; and, finally, against death itself, which then forced itself upon his consideration.

C.H. Spurgeon Reformed Baptist @princeofpreachers

David complains before his loving God of the worst weapon of his enemies' attacks, and the bitterest drop of his distresses. "Oh!" saith David, "many there be that say of my soul, There is no help for him in God." Some of his distrustful friends said this sorrowfully, but his enemies exultingly boasted of it, and longed to see their words proved by his total destruction.

Matthew Henry Presbyterian @wholebiblehenry

The title of this psalm and many others is as a key hung ready at the door, to open it, and let us into the entertainments of it; when we know upon what occasion a psalm was penned we know the better how to expound it.
