And it came to pass at the end of twenty years, wherein Solomon had built the house of the LORD, and his own house,

twenty. The number of Expectancy and Waiting, 2 Chronicles 21:1 . Divine completeness (21) minus one (1). ( App-10 ). Compare Genesis 31:38 , Genesis 31:41 .Judges 4:3 ; Judges 15:20 ; Judges 16:31 . 1 Samuel 7:2 .

And Solomon went to Hamath-zobah, and prevailed against it.

But of their children, who were left after them in the land, whom the children of Israel consumed not, them did Solomon make to pay tribute until this day.

And he appointed, according to the order of David his father, the courses of the priests to their service, and the Levites to their charges, to praise and minister before the priests, as the duty of every day required: the porters also by their courses at every gate: for so had David the man of God commanded.

porters = gatekeepers. Compare 1 Chronicles 9:17 .
the man of God. See App-49 .

by the hands of. Figure of speech Pleonasm.
ships. From Tyre, in the Mediterranean, to the Red Sea. To show that this was not insuperable (as some have imagined) the next clause is added.
that had knowledge of the sea. This is the explanation of the possibility of such voyages being possible. And why not?
Ophir. First occurrence Genesis 10:29 , where Ophir, the son of Joktan, was the ancestor of several Arabian tribes. Rhodesia is probably the land indicated. About five hundred ruins are scattered over a large area. There are evidences' of gold-smelting in the great Zimbawe buildings, where the ancient ruins resemble the ruins in Syria, temple and fortress being combined. Tharshish ships for Ezion-geber sailed thither to Fast Africa, as well as to Arabia and India. The Queen of Sheba being mentioned in close connection with Ophir (2 Chronicles 8:10 ), as hearing about Solomon, furnishes further evidence. Compare 1 Kings 9:28 .
