And they sing the song of Moses the servant of God, and the song of the Lamb. Most probably the song of deliverance after the passage of the Red Sea (Exodus 15:1-27.), to which this bears a general resemblance.
Moses is called the "servant of God" in Exodus 14:31 and elsewhere. The song of Moses is also the song of the Lamb; the Old Testament and the New Testament Churches are one. Saying, Great and marvellous are thy works, Lord God Almighty (cf.
Exodus 15:7, "And in the greatness of thine excellency thou hast overthrown them;" also Psalms 111:2; Psalms 139:14). This song, like that in Revelation 4:8, is addressed to the "Lord God Almighty." Just and true are thy ways, thou King of saints.
The reading of the Textus Receptus, ἁγίων, "of saints," is certainly incorrect. It does not appear in any Greek manuscripts, but was inserted by Erasmus to represent the sanctorum of his Vulgate, which word, however, is itself a corruption of saeculorum, the true Vulgate reading representing αἰώνων.
ἐθνῶν, "of nations," is read in א, A, B, P, 1, 7, 8, 14. etc., An-dress, Primasius; while αἰώνον, "of ages," is the reading of א, C, 95, Vulgate, etc. It has been conjectured that αιθνων (by itacism for ἐθνῶν) has been confused with αιωνων.
a parallel to the reading, " King of nations" is found in Jeremiah 10:7, Hebrew text and Theodotion, but not LXX.: "Who would not fear thee, O King of nations?" which is very like the succeeding clause in Jeremiah 10:5, especially in connection with the "nations" there mentioned.
The title "King of the ages," or "eternal King," is applied to God in 1 Timothy 1:17, and in the Book of Tobit twice (13:6 and 10), but seems unknown to the Old Testament.
