During this halt they prepared that great song of triumph which St. John heard sung by them who had been victorious over the beast, standing by the sea of glass, having the harps of God. For by that calmer sea, triumphant over a deadlier persecution, they still found their adoration and joy expressed in this earliest chant of sacred victory. Because all holy hearts give like thanks to Him Who sitteth upon the throne, therefore “deep answers unto deep,” and every great crisis in the history of the Church has legacies for all time and for eternity; and therefore the triumphant song of Moses the servant of God enriches the worship of heaven, as the penitence and hope and joy of David enrich the worship of the Church on earth (Rev. xv. 3). Like all great poetry, this song is best enjoyed when it is neither commented upon nor paraphrased, but carefully read and warmly felt. There are circumstances and lines of thought which it is desirable to point out, but only as a preparation, not a substitute, for the submission of a docile mind to the influence of the inspired poem itself. It is unquestionably archaic. The parallelism of Hebrew verse is already here, but the structure is more free and unartificial than that of later poetry; and many ancient words, and words of Egyptian derivation, authenticate its origin. So does the description of Miriam, in the fifteenth verse, as “the prophetess, the sister of Aaron.” In what later time would she not rather have been called the sister of Moses? But from the lonely youth who found Aaron and Miriam together as often as he stole from the palace to his real home—the lonely man who regained both together when he returned from forty years of exile, and who sometimes found them united in opposition to his authority (Num. xii. 1, 2)—from Moses alone the epithet is entirely natural. It is also noteworthy that Philistia is mentioned first among the foes who shall be terrified (ver. 14, R.V.), because Moses still expected the invasion to break first on them. But the unbelieving fears of Israel changed the route, so that no later poet would have set them in the forefront of his song. Thus also the terror of the Edomites is anticipated, although in fact they sturdily refused a passage to Israel through their land (Num. xx. 20). All this authenticates the song, which thereupon establishes the miraculous deliverance that inspired it. The song is divided into two parts. Up to the end of the twelfth verse it is historical: the remainder expresses the high hopes inspired by this great experience. Nothing now seems impossible: the fiercest tribes of Palestine and the desert may be despised, for their own terror will suffice to “melt” them; and Israel may already reckon itself to be guided into the holy habitation (ver. 13).
