At the end of a devastating plague, a defining moment occurs that establishes the permanent location of the future Temple. King David refuses to take shortcuts in his service to God. He takes a principled stand that a true sacrifice requires personal cost and full payment, rather than relying on the generosity of others. David makes it clear to Araunah the Jebusite that he will purchase the property for its full value [מצודת ציון]. He firmly refuses to offer God a sacrifice that costs him nothing, insisting instead on buying the threshing floor and the cattle with his own money [מצודת דוד].
A notable discrepancy arises regarding the purchase price, as this account mentions fifty silver shekels, while another historical record states David paid six hundred gold shekels. Commentators offer two main ways to understand this difference. One perspective suggests that David collected fifty shekels of silver from each of the twelve tribes, accumulating a total of six hundred. Although the payment was made in silver, its weight and value were equivalent to gold [רש״י, רד״ק, אברבנאל]. However, the primary approach among commentators presents a two-stage purchasing process. Initially, David bought only the small area of the threshing floor needed for the altar, along with the cattle and wood, for fifty silver shekels. Later, when fire descended from heaven onto the altar and David realized this was the chosen site for the entire Temple, he purchased the entire surrounding field for six hundred gold shekels [מצודת דוד, רד״ק, מלבי״ם, אברבנאל].
Beyond the transaction itself, this event holds deep historical and spiritual meaning. The chosen location is not random; it is Mount Moriah, the site of the binding of Isaac. This specific place was designated long in advance to house the presence of God and to serve as His ultimate spiritual center [אברבנאל]. Discovering this location brings a profound sense of closure for David. He had spent his entire life worrying and searching for a permanent home for God. At the end of his life, God honors him by stopping the plague through his sacrifices and clearly revealing the Temple's location. By purchasing the land and preparing the materials for the building that his son Solomon would eventually construct, it is considered as though David built the house himself [אברבנאל].
Ultimately, the halting of the plague and the discovery of the Temple site serve as a powerful lesson for the people. These events prove to the nation that their safety and security do not depend on armies or military strength, but rest entirely on the supervision and care of God [מלבי״ם].
