David"s mention of the Lord"s sword may mean he expected God to use a human army to deliver him, or this may be just a metaphorical way of speaking about deliverance. His description of the wicked draws attention to the fact that they live only for the present. They are content with the many blessings God gives all people in this life through His "common grace." They occupy themselves entirely with their families and estates to the exclusion of spiritual matters. [source][source][source]
