The conquest of the Ammonite capital reaches its peak with a powerful symbol of victory and the transfer of power. David claims the magnificent crown of the conquered realm. The original owner of this crown is a matter of discussion; it may have belonged to the Ammonite king himself, or it could have been the crown placed upon the chief Ammonite idol, known as Molech or Milcom [מצודת ציון, ביאור שטיינזלץ]. Embedded within this royal headpiece was a highly significant and valuable precious stone [מצודת ציון, רש״י].
A notable physical challenge arises regarding the sheer mass of the crown, which is recorded as weighing a full talent of gold. This raises the question of how any human could bear such a heavy load upon their head. To resolve this, several explanations are offered. One approach suggests that the crown was indeed placed directly on David's head, but only for a brief, temporary moment, allowing him to support the immense weight just once or twice [רד״ק].
A different and prominent perspective argues that the crown never actually rested on David's head at all. Instead, it was suspended in the air from above. David would sit on his royal throne directly beneath it, creating the visual illusion for onlookers that he was wearing it—a practice recognized as a royal custom in Arab lands [רש״י, רד״ק, מצודת דוד]. Drawing upon the wisdom of the early sages, another explanation offers a more wondrous solution: the precious stone set in the crown was actually a lodestone, a natural magnet, which kept the heavy crown suspended in the air just above his head [רש״י, רד״ק]. Alternatively, the stated measurement might not refer to the physical mass of the crown at all. Instead, it could indicate its financial worth, meaning that the precious stone alone held the monetary value of a talent of gold [רד״ק]. Following this symbolic transfer of power, David proceeds to carry away a massive amount of spoils from the newly conquered city [ביאור שטיינזלץ].
