The light is focussed and set in a tower that it may shine out over sea and storm. The fire is gathered into a brasier that it may warm all the house. Some commentators take that strong expression "the trust of all the ends of the earth" as asserting that even the confidences of idolaters in their gods are at bottom trust in Jehovah and find their way to Him. But such a view of idolatry is foreign to the Old Testament, and is not needed to explain the psalmist's words. God is the only worthy object of trust, and remains so whether men do in fact trust Him or not. And one day, thinks the psalmist, God's patient manifestation of His grace to Israel will tell, and all men will come to know Him for what He is. "The remotest sea" is not translation, but paraphrase. The psalmist speaks in vague terms, as one who knew not what lay beyond the horizon of that little-traversed western ocean. Literally his words are "the sea of the remote [peoples]"; but a possible emendation has been suggested, reading instead of _sea_ "regions" or "nations." The change is slight, and smooths an awkward expression, but destroys the antithesis of earth and sea, and makes the second clause a somewhat weak repetition of the first. From the self-revelation of God in history the psalm passes to His mighty deeds in nature (vv. 6, 7 _a_), and from these it returns to His providential guidance of human affairs (ver. 7 _b_). The two specimens of Divine power celebrated in vv. 6, 7, are suggested by the closing words of ver. 5. "The ends of the earth" were, according to ancient cosmography, girdled by mountains; and God has set these fast. The dash of "the remotest seas" is hushed by Him. Two mighty things are selected to witness to the Mightier who made and manages them. The firm bulk of the mountains is firm because He is strong. The tossing waves are still because He bids them be silent. How transcendently great then is He, and how blind those who, seeing hill and ocean, do not see God! The mention of the sea, the standing emblem of unrest and rebellious power, suggests the "tumult of the peoples," on which similar repressive power is exercised. The great deeds of God, putting down tyranny and opposition to Israel, which is rebellion against Himself, strike terror, which is wholesome and is purified into reverence, into the distant lands; and so, from the place where the sun rises to the "sad-coloured end of evening" where it sinks in the west, _i.e._, through all the earth, there rings out a shout of joy. Such glowing anticipations of universal results from the deeds of God, especially for Israel, are the products of diseased national vanity, unless they are God-taught apprehension of the Divine purpose of Israel's history, which shall one day be fulfilled, when the knowledge of the yet more wondrous deeds which culminated in the Cross is spread to the ends of the earth and the remotest seas.
