The transgressors will have a tragic end for their actions, but there will be a happy end for the man of peace.
The Psalmist David understood that for the bad people their moment would arrive. David believed in the Lord and in His promises, that everyone who persecuted Him would have their reward. In the same way the righteous will also have a just reward:
Consider the blameless, observe the upright;
a future awaits those who seek peace.
What does a righteous person do, or what can an honest person do? The righteous practices justice with others, the person with integrity is faithful in everything they do, because if is they are faithful to their Lord, how much more with their neighbor.
