New Defender's Study Bible Notes
12:6 fourfold. David’s pronouncement of a “fourfold” restoration against Nathan’s hypothetical sinner came back on his own house. First there was the death of his child (II Samuel 12:18); then came the rape of his virgin daughter Tamar by her half-brother Amnon (II Samuel 13:1,14). This led to Amnon’s vengeful murder by Tamar’s brother Absalom (II Samuel 13:28-29). Fourth was the treason and death of Absalom (II Samuel 18:9,14). David was greatly blessed by God, but even the godliest of men, particularly if they are in positions of influence, cannot enter into such flagrant willful sin as did David without also receiving divine chastening.
