Psalms 74:23

Forget not the voice of thine enemies -The voice of thine enemies clamoring for the destruction of thy people. ComparePsalms 137:7. The prayer is, that God would bring deserved chastisement upon them for their purposes and their aims against his people. It is not necessarily a prayer for vengeance; it is a prayer for just retribution. The tumult of those that rise up against thee -Of those that make war on thee, and on thy people. The word ““tumult” here means clamor or shout - as the shout of battle. The reference is to the movement of a host pressing on to conquest, encouraging and exciting each other, and endeavoring to intimidate their enemies by the loud clamor of the war-cry.
