1 Kings 10:27

Made silver as stones - This strong hyperbole marks in the most striking way the great wealth and prosperity of the capital during Solomon’s reign. The lavish expenditure which impoverished the provinces, and produced, or helped to produce, the general discontent that led to the outbreak under Jeroboam, enriched the metropolis, which must have profited greatly by the residence of the court, the constant influx of opulent strangers, and the periodical visits of all Israelites not hindered by some urgent reason at the great festivals.

The “sycomore-trees in the vale” (Shephelah) are mentioned also in 1 Chronicles 27:28. Like the olives and the vines, they were placed by David under a special overseer, on account of their value. The tree meant seems to be the sycomore proper, or “fig-mulberry,” which is still common in Palestine, and is highly esteemed both on account of its fruit and its timber.
