During the reign of King Solomon, Jerusalem reached a peak of economic prosperity. Rare and precious resources became an inseparable part of the everyday landscape. This immense wealth did not remain locked away in royal treasuries; rather, it flowed freely into the public spaces and deeply enriched the lives of the local residents.
The sheer volume of silver in the city was staggering. The primary approach among commentators is that describing silver as being as common as stones is an exaggeration, meant to illustrate an abundance so great that precious metals felt as ordinary as the pebbles in the street. However, a more practical perspective suggests that massive blocks of silver were actually left out in the city squares. These pieces were so enormous and heavy—reaching sizes of eight to ten cubits—that they were impossible to steal, allowing them to rest in the open like simple paving stones [מצודת דוד, רד״ק]. Interestingly, there is a chronological shift in how this wealth was viewed. While at one point silver was considered completely worthless, its status eventually changed to being compared to stones. This shift in the appreciation of silver occurred after Solomon married the daughter of Pharaoh [רש״י].
A similar transformation occurred with the city's building materials. Highly prized cedar wood became as ordinary as the sycamore, a simple, inferior tree that grows in massive quantities in the lowlands and valleys [מצודת דוד, מצודת ציון]. The imported cedars became completely normal and widely available [ביאור שטיינזלץ]. This was possible because the booming international trade and the influx of foreign visitors brought immense wealth to the general public. The king was not the only one who could afford luxury; any wealthy resident of Jerusalem had the means to build a home out of imported cedar, making the premium wood a standard feature of the local architecture [מלבי״ם].
