Problem: In this verse, we are informed that “Samuel judged Israel all the days of his life.” However, Samuel lived after Saul was anointed king (1 Sam. 8:5; 12:1; 25:1).
Solution: Samuel only gave up his civil authority to Saul, not his spiritual authority. Under Israel’s monarch there was a separation of power. Kings were forbidden to perform spiritual functions (cf. 2 Chron. 26:16–23), and the prophets no longer had political authority. Even so, the prophets, with their direct revelations from God, were a continual moral check on those in political power.
