2 Samuel 12:30
And he took their king’s crown from off his head, the weight whereof was a talent of gold with the precious stones: and it was set on David’s head. And he brought forth the spoil of the city in great abundance. And he took their king’s crown from off his head, the weight whereof was a talent of gold with the precious stones: and it was set on David’s head. And he brought forth the spoil of the city in great abundance.
2 Samuel 12:30 belongs to the account of David's sin with Bathsheba and his murder of Uriah and its consequences. In that account the verse follows David's plan to make Uriah the bearer of his own death-warrant, sending by his hand a letter to Joab commanding Joab to set Uriah in the forefront of the hottest battle and retire from him that he might be smitten and die. Joab, already stained with the guilt of one wanton murder, obeyed without hesitation, and Uriah fell by the sword of the children of Ammon. The verse comes after Joab sent a carefully worded message that Uriah the Hittite was dead also, and David answered with cold indifference that the sword devours one as well as another and Joab should make the battle stronger against the city and overthrow it.
Its setting is when David had departed from God and yielded himself to the wicked one, yet still held the position and authority God had given him. It shows David exercising God-given power contrary to divine law and claiming an obedience that would imperil the soul of him who yielded it, as Joab did when he transgressed God's law because the king commanded it. The setting contrasts with David's earlier course of keeping God's Word before him as king and standing firm, but when he turned from its teachings he damaged his good name. Royal power and victory do not prevent the harm and consequences that follow turning from God's commands.
