10:29 Chariot - This is not to be understood of the chariots and horses themselves, but for the lading of chariots and horses, which consisting of fine linen and silk, were of great value: and the king's custom, together with the charges of the journey, amounted to these sums. Hittites - A people dwelling principally in the northern and eastern parts of Canaan, Josh 1:4, whom the Israelites, contrary to their duty, suffered to live amongst them, Judg 3:5, who afterwards grew numerous and potent, and, it may be, sent out colonies (after the manner of the ancient times) into some parts of Syria and Arabia. And possibly, these kings of the Hittites may be some of those kings of Arabia, ver.15.
10:14-29 Solomon increased his wealth. Silver was nothing accounted of. Such is the nature of worldly wealth, plenty of it makes it the less valuable; much more should the enjoyment of spiritual riches lessen our esteem of all earthly possessions. If gold in abundance makes silver to be despised, shall not wisdom, and grace, and the foretastes of heaven, which are far better than gold, make gold to be lightly esteemed? See in Solomon's greatness the performance of God's promise, and let it encourage us to seek first the righteousness of God's kingdom. This was he, who, having tasted all earthly enjoyments, wrote a book, to show the vanity of all worldly things, the vexation of spirit that attends them, and the folly of setting our hearts upon them: and to recommend serious godliness, as that which will do unspeakably more to make us happy, that all the wealth and power he was master of; and, through the grace of God, it is within our reach.
