9:15-28 Here is a further account of Solomon's greatness. He began at the right end, for he built God's house first, and finished that before he began his own; then God blessed him, and he prospered in all his other buildings. Let piety begin, and profit follow; leave pleasure to the last. Whatever pains we take for the glory of God, and to profit others, we are likely to have the advantage. Canaan, the holy land, the glory of all lands, had no gold in it; which shows that the best produce is that which is for the present support of life, our own and others; such things did Canaan produce. Solomon got much by his merchandise, and yet has directed us to a better trade, within reach of the poorest. Wisdom is better than the merchandise of silver, and the gain thereof than fine gold, Pr 3:14.

the wall of Jerusalem—either repairing some breaches in it (1Ki 11:27), or extending it so as to enclose Mount Zion.

Hazor—fortified on account of its importance as a town in the northern boundary of the country.

Megiddo—(now Leijun)—Lying in the great caravan road between Egypt and Damascus, it was the key to the north of Palestine by the western lowlands, and therefore fortified.

Gezer—on the western confines of Ephraim, and, though a Levitical city, occupied by the Canaanites. Having fallen by right of conquest to the king of Egypt, who for some cause attacked it, it was given by him as a dowry to his daughter, and fortified by Solomon.
