C.H. Spurgeons's The Treasury of David
Verse 8. He shall have dominion also from sea to sea. Wide spread shall be the rule of Messiah; only the Land's End shall end his territory: to the Ultima Thule shall his sceptre be extended. From Pacific to Atlantic, and from Atlantic to Pacific, he shall be Lord, and the oceans which surround each pole shall be beneath his sway. All other power shall be subordinate to his; no rival nor antagonist shall he know. Men speak of the Emperor of all the Russias, but Jesus shall be Ruler of all mankind.
And from the river unto the ends of the earth. Start where you will, by any river you choose, and Messiah's kingdom shall reach on to the utmost bounds of the round world. As Solomon's realm embraced all the land of promise, and left no unconquered margin; so shall the Son of David rule all lands given him in the better covenant, and leave no nation to pine beneath the tyranny of the prince of darkness. We are encouraged by such a passage as this to look for the Saviour's universal reign; whether before or after his personal advent we leave for the discussion of others. In this Psalm, at least, we see a personal monarch, and he is the central figure, the focus of all the glory; not his servant, but himself do we see possessing the dominion and dispensing the government. Personal pronouns referring to our great King are constantly occurring in this Psalm; he has dominion kings fall down before him, and serve him; for he delivers, he spares, he saves, he lives, and daily is he praised.
EXPLANATORY NOTES AND QUAINT SAYINGS
Verse 8. From the river. There are many modern interpreters who, from the mention of the "river" -- namely, the river Euphrates -- in the other clause of the verse, think that the boundaries of the land of Palestine are here to be understood, that country being described as extending from the Red Sea to the Sea of Syria, otherwise called the Sea of the Philistines, and the Great Sea; and from the Euphrates to the Great Desert lying behind Palestine and Egypt. These are the limits of the Israelitish territory: the former, from the south to the west; the latter, from the north to the east. (Genesis 15:18.) But, in this passage, there can scarcely be a doubt that by the river -- to wit, the Euphrates -- is indicated the extreme boundary of the earth towards the east. In a highly poetical, magnificent description, such as is given in this song, of a king exalted above all others, nothing can be conceived more inappropriate than saying that the dominions of such a king should be bounded by the limits of Palestine.

Verse 8. The universal spread of the gospel. Other theories as to the future overturned, and their evil influence exposed; while the benefit and certainty of this truth is vindicated.
