Galatians 6:7 Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap.
[Patriarchs & Prophets pp. 727>728] “He shall restore fourfold,” had been David's unwitting sentence upon himself, on listening to the prophet Nathan's parable; and according to his own sentence he was to be judged. Four of his sons must fall, and the loss of each would be a result of the father's sin. The shameful crime of Amnon, the first-born, was permitted by David to pass unpunished and unrebuked. The law pronounced death upon the adulterer, and the unnatural crime of Amnon made him doubly guilty. But David, self-condemned for his own sin, failed to bring the offender to justice.
For two full years Absalom, the natural protector of the sister so foully wronged, concealed his purpose of revenge, but only to strike more surely at the last. At a feast of the king's sons the drunken, incestuous Amnon was slain by his brother's command. Twofold judgment had been meted out to David. The terrible message was carried to him, “Absalom hath slain all the king's sons, and there is not one of them left. Then the king arose, and tare his garments, and lay on the earth; and all his servants stood by with their clothes rent.” The king's sons, returning in alarm to Jerusalem, revealed to their father the truth; Amnon alone had been slain; and they “lifted up their voice and wept: and the king also and all his servants wept very sore.”
But Absalom fled to Talmai, the king of Geshur, his mother's father. Like other sons of David, Amnon had been left to selfish indulgence. He had sought to gratify every thought of his heart, regardless of the requirements of God. Notwithstanding his great sin, God had borne long with him. For two years he had been granted opportunity for repentance; but he continued in sin, and with his guilt upon him, he was cut down by death, to await the awful tribunal of the judgment. David had neglected the duty of punishing the crime of Amnon, and because of the unfaithfulness of the king and father and the impenitence of the son, the Lord permitted events to take their natural course, and did not restrain Absalom.
When parents or rulers neglect the duty of punishing iniquity, God Himself will take the case in hand. His restraining power will be in a measure removed from the agencies of evil, so that a train of circumstances will arise which will punish sin with sin. The evil results of David's unjust indulgence toward Amnon were not ended, for it was here that Absalom's alienation from his father began. After he fled to Geshur, David, feeling that the crime of his son demanded some punishment, refused him permission to return. And this had a tendency to increase rather than to lessen the inextricable evils in which the king had come to be involved.
Exodus 34:6 And the Lord passed by before him, and proclaimed, The Lord, The Lord God, merciful and gracious, longsuffering, and abundant in goodness and truth, 7 Keeping mercy for thousands, forgiving iniquity and transgression and sin, and that will by no means clear the guilty; visiting the iniquity of the fathers upon the children, and upon the children's children, unto the third and to the fourth generation.
May The Lord add His blessing to the study of His word. God bless!
