3. A promise of future praise 79:13

The psalmist promised God's people would reward Him with unceasing praise if He would give them deliverance. He viewed the people as God's helpless sheep. He said their praise would be public from then on for this salvation.

It is appropriate to petition God for vengeance when enemies defeat God's people and consequently make Him look bad. He will deliver eventually because He has promised to preserve His own. However, discipline may continue a long time if sin has been gross.
