David’s words (Psalms) are words that have been approved, inspired by God. The one who rules in the affairs of man must be one who renders justice properly. Subjects will look upon his rule as with much pleasure and satisfaction as they look out at a clear sky in the morning hours. Those who are rebellious, on the other hand, will be as thorn bushes discarded (23:1-7). The remainder of the chapter focuses on David men in their military capacity (23:8-39).
Application: As you consider the military victories that David’s men had gained it might be easy to think that military prowess is a virtue of and from God. This would be a mistake. Without the Lord taking the lead to establish David what military victories were gained by his men would have been defeats.
