Solomon’s empire, like all the great empires of Asia down to the time of the Persians, consisted of a congeries of small kingdoms, all ruled by their own kings 1 Kings 4:24, who admitted the suzerainty of the Jewish monarch, and paid him “presents,” i. e., an annual tribute (see 1 Kings 10:25).
Unto the land of the Philistines - There is no word corresponding to “unto” in the Hebrew. The construction should be, “Solomon reigned over all the kingdoms from the river (i. e., the Euphrates: see the marginal references), over the land of the Philistines,” etc. The writer draws attention to the fact that the extent of Solomon’s kingdom was in accordance with the promises made to Abraham, Moses, and Joshua.
