He shall have dominion also from sea to sea, and from the river unto the ends of the earth. He shall have dominion also from sea to sea - The best comment on this, as it refers to Solomon, may be found in 1 Kings 4:21, 1 Kings 4:24 : "And Solomon reigned over all kingdoms, from the river unto the land of the Philistines, and unto the border of Egypt; for he had dominion over all on this side the river, from Tiphsah even to Azzah, over all the kings on this side the river; and he had peace on all sides round about him."
Solomon, it appears, reigned over all the provinces from the river Euphrates to the land of the Philistines, even to the frontiers of Egypt. The Euphrates was on the east of Solomon's dominions; the Philistines were westward, on the Mediterranean sea; and Egypt was on the south. Solomon had therefore, as tributaries, the kingdoms of Syria, Damascus, Moab, and Ammon, which lay between the Euphrates and the Mediterranean. Thus he appears to have possessed all the land which God covenanted with Abraham to give to his posterity.
Unto the ends of the earth - Or land, must mean the tract of country along the Mediterranean sea, which was the boundary of the land on that side: but, as the words may refer to Christ, every thing may be taken in its utmost latitude and extent.
