Now in the first Psalm, David links prosperity with the keeping of the law of God. And many places in the Scriptures these things are linked together. When Moses turned over the reins to Joshua, he commanded him to meditate in the law and in the commandments. "And thus shalt thou make thy way prosperous, and thus shalt thou have good success" ( Joshua 1:8 ). Now David is again linking a prosperous reign to obedience to the law, the statutes, the judgments, the commandments of God. In other words, the law is God's rules for a happy, prosperous life.
