"Who is like Thee, glorious in holiness, Fearful in praises, doing wonders? ... Thou in Thy mercy hast led the people which Thou has redeemed: Thou hast guided them in Thy strength to Thy holy habitation. The peoples have heard, they tremble.... Terror and dread falleth upon them; By the greatness of Thine arm they are as still as a stone; Till Thy people pass over, O Lord, Till the people pass over which Thou hast purchased. Thou shalt bring them in, and plant them in the mountain of Thine inheritance, The place, O Lord, which Thou hast made for Thee to dwell in.” Exodus 15:1-16 , R.V. PP 288.1"
"Then sang Moses and the children of Israel this song unto the Lord, and spake, saying, I will sing unto the Lord, for he hath triumphed gloriously: the horse and his rider hath he thrown into the sea. The Lord is my strength and song, and he is become my salvation: he is my God, and I will prepare him an habitation; my father’s God, and I will exalt him. The Lord is a man of war: the Lord is his name. Pharaoh’s chariots and his host hath he cast into the sea: his chosen captains also are drowned in the Red sea. The depths have covered them: they sank into the bottom as a stone. Thy right hand, O Lord, is become glorious in power: thy right hand, O Lord, hath dashed in pieces the enemy. And in the greatness of thine excellency thou hast overthrown them that rose up against thee: thou sentest forth thy wrath, which consumed them as stubble. And with the blast of thy nostrils the waters were gathered together, the floods stood upright as an heap, and the depths were congealed in the heart of the sea. The enemy said, I will pursue, I will overtake, I will divide the spoil; my lust shall be satisfied upon them; I will draw my sword, my hand shall destroy them. Thou didst blow with thy wind, the sea covered them: they sank as lead in the mighty waters. Who is like unto thee, O Lord, among the gods? who is like thee, glorious in holiness, fearful in praises, doing wonders? Thou stretchedst out thy right hand, the earth swallowed them. Thou in thy mercy hast led forth the people which thou hast redeemed: thou hast guided them in thy strength unto thy holy habitation. The people shall hear, and be afraid: sorrow shall take hold on the inhabitants of Palestina. Then the dukes of Edom shall be amazed; the mighty men of Moab, trembling shall take hold upon them; all the inhabitants of Canaan shall melt away. Fear and dread shall fall upon them; by the greatness of thine arm they shall be as still as a stone; till thy people pass over, O Lord, till the people pass over, which thou hast purchased."
Ellen White directly references Exodus 15:1-16 in this passage.
"Who is like unto thee, O Lord, among the gods? who is like thee, glorious in holiness, fearful in praises, doing wonders?"
EGW quotes directly from Exodus 15:11 and other verses in the chapter, indicating a clear and intentional reference to the Song of Moses after the crossing of the Red Sea.
"Like the voice of the great deep, rose from the vast hosts of Israel that sublime ascription. It was taken up by the women of Israel, Miriam, the sister of Moses, leading the way, as they went forth with timbrel and dance. Far over desert and sea rang the joyous refrain, and the mountains re-echoed the words of their praise—“Sing ye to Jehovah, for He hath triumphed gloriously.” PP 288.2"
"And Miriam answered them, Sing ye to the Lord, for he hath triumphed gloriously; the horse and his rider hath he thrown into the sea."
EGW directly quotes and elaborates on the verse.
