After God delivers David from his enemies, David declares God’s holiness:

Psa 7:17  I will thank the LORD because he is just; I will sing praise to the name of the LORD Most High.

Again we are reminded that the courts don’t always deliver fair verdicts and the governments taxes and policies aren’t always just.  

The only true and flawless judgements come from God.  

As God smashes down David’s enemies, David reminds us that The Most High God is the only judge who gets it right.
