In vain also do they object that what we have established from Scripture in the books of Kings and Chronicles—that when God wills the accomplishment of something which ought not to be done except by people who will it, their hearts will be inclined to will this, with God producing this inclination, who in a marvelous and ineffable way works also in us that we will—is not pertinent to the subject with which we are dealing—St Augustine

However, the tribe of Judah did not fail until he came for whom it was reserved, who did not himself sit upon a material throne, for the kingdom of Judea had now been transferred to Herod, the son of Antipater, the Ascalonite, and to his sons, who divided Judea into four provinces when Pilate was governor and Tiberius held the power over the whole Roman province (Lk 3:1). But his indestructible kingdom he calls the throne of David on which the Lord sat. He himself is "the expectation of nations," (Gen 49:10 LXX) not of the least part of the world. "For there will be the root of Jesse," it is said, (Is 11:10 LXX) "and he who rises up to rule the Gentiles, in him the Gentiles will hope." "For I have placed you for a covenant of the people, for a light of the Gentiles." (Is 42:6) "And I shall establish," it is said, ―his seed forever, and his throne as the days of the heavens."―St Basil the Great

Although he [Saul] was a king, he sinned if he killed the innocent. Finally, even David, when he was in possession of his kingdom and had heard that an innocent man named Abner was slain by Joab, the leader of his army, said, "I and my kingdom are innocent now and forever of the blood of Abner the son of Ner," and he fasted in sorrow.

These things I have written not to disconcert you but that the example of kings may stir you to remove this sin from your kingdom, for you will remove it by humbling your soul before God.4 You are a man, you have met temptation—conquer it. Sin is not removed except by tears and penance. No angel or archangel can remove it; it is God himself who alone can say, "I am with you";(1 Cor 15:50) if we have sinned, he does not forgive us unless we do penance―St Ambrose of Milan
