Which side of the door do _you_ mean to be on?
'There is a river, the streams whereof shall make glad the city of God, the holy place of the tabernacles of the most High. 5. God is in the midst of her; she shall not be moved: God shall help her, and that right early. 6. The heathen raged, the kingdoms were moved: He uttered His voice, the earth melted. 7. The Lord of hosts is with us; the God of Jacob is our refuge.'--PSALM xlvi 4-7.
There are two remarkable events in the history of Israel, one or other of which most probably supplied the historical basis upon which this psalm rests. One is that wonderful deliverance of the armies of Jehoshaphat from the attacking forces of the bordering nations, which is recorded in the twentieth chapter of the Book of Chronicles. There you will find that, by a singular arrangement, the sons of Korah, members of the priestly order, were not only in the van of the battle, but celebrated the victory by hymns of gladness. It is possible that this may be one of those hymns; but I think rather that the more ordinary reference is the correct one, which sees in this psalm and in the two succeeding ones, echoes of that supernatural deliverance of Israel in the time of Hezekiah, when
'The Assyrian came down like a wolf on the fold,'
and Sennacherib and all his army were, by the blast of the breath of His nostrils, swept into swift destruction.
The reasons for that historical reference may be briefly stated. We find, for instance, a number of remarkable correspondences between these three psalms and portions of the Book of the prophet Isaiah, who, as we know, lived in the period of that deliverance. The comparison, for example, which is here drawn with such lofty, poetic force between the quiet river which 'makes glad the city of God,' and the tumultuous billows of the troubled sea, which shakes the mountain and moves the earth, is drawn by Isaiah in regard to the Assyrian invasion, when he speaks of Israel refusing 'the waters of Shiloah, which go softly,' and, therefore, having brought upon them the waters of the river--the power of Assyria--'which shall fill the breadth of Thy land, O Immanuel!' Notice, too, that the very same consolation which was given to Isaiah, by the revelation of that significant appellation, 'Immanuel, God with us,' appears in this psalm as a kind of refrain, and is the foundation of all its confident gladness, 'The Lord of Hosts is with us.' Besides these obvious parallelisms, there are others to which I need not refer, which, taken together, seem to render it at least probable that we have in this psalm the devotional echo of the great deliverance of Israel from Assyria in the time of Hezekiah.
Now, these verses are the cardinal central portion of the song. We may call them The Hymn of the Defence and Deliverance of the City of God. We cannot expect to find in poetry the same kind of logical accuracy in the process of thought which we require in treatises; but the lofty emotion of devout song obeys laws of its own: and it is well to surrender ourselves to the flow, and to try to see with the Psalmist's eyes for a moment his sources of consolation and strength.
I take the four points which seem to be the main turning-points of these verses--first, the gladdening river; second, the indwelling Helper; third, the conquering voice; and fourth, the alliance of ourselves by faith with the safe dwellers in the city of God.
I. First, we have the gladdening river--an emblem of many great and joyous truths.
The figure is occasioned by, or at all events derives much of its significance from, a geographical peculiarity of Jerusalem. Alone among the great cities and historical centres of the world, it stood upon no broad river. One little perennial stream, or rather rill of living water, was all which it had; but Siloam was mightier and more blessed for the dwellers in the rocky fortress of the Jebusites than the Euphrates, Nile, or Tiber for the historical cities which stood upon their banks. One can see the Psalmist looking over the plain eastward, and beholding in vision the mighty forces which came against them, symbolised and expressed by the breadth and depth and swiftness of the great river upon which Nineveh sat as a queen, and then thinking upon the little tiny thread of living water that flowed past the base of the rock upon which the temple was perched. It seems small and unconspicuous--nothing compared to the dash of the waves and the rise of the floods of those mighty secular empires, still, 'There is a river the streams whereof shall make glad the city of God.' Its waters shall never fail, and thirst shall flee whithersoever this river comes.
