Help me, O LORD my God: O save me according to thy mercy:
The verse asks the Lord God for help and for salvation measured by His mercy. It belongs to an appeal for justice in which those who scheme against the innocent reap the consequences of their own evil. The stern pronouncements surrounding it are God's own verdict upon the wicked, announcing the penalties their deeds merit. They are not to be read as David's personal prayer wishing injury upon his foes.
