2 Samuel 5:3

A league. The early kings of Israel were not invested with despotic power. Thus, on Saul's appointment, "Samuel wrote in a book the manner of the kingdom". The revolt against Rehoboam was the result of the too great extension of the royal power in the days of Solomon ( 1 Kings 12:4 ). Though subsequently the kings seemed to have retained their supremacy, yet when the good and patriotic Jehoiada restored the family of David to the throne, he reverted to the old ways, and "made a covenant between the king and the people" ( 2 Kings 11:17 ). Besides personal rights, the tribes, accustomed to their own leaders, and unused to yield obedience to a central authority, would certainly stipulate for a large measure of tribal independence, and the management of local matters by themselves. They anointed David king. This was the public ratification of Samuel's anointing, and by it David became de facto, as well as de jure, king. The prophets could not give any right over the people without the consent of the people themselves. But all religious men would see in the Divine command an obligation upon their conscience to accept as their king the man whom the prophet had anointed; and Saul acted in an irreligious manner in seeking to frustrate God's will. And this impiety culminated in his murder of the priests at Nob, which was the open avowal that he would trample all scruples of conscience underfoot.
