Ye shall have a song,.... That is, the Jews should have a song, and sing it upon the ruin of the Assyrian army; as the Israelites had, when Pharaoh and his host were drowned in the Red Sea; and so will the Christian church have one, at the fall of Babylon, Re 15:1:as in the night, [when] a holy solemnity is kept; and gladness of heart, the Jewish feasts always began, the even preceding, and were ushered in with singing songs, and psalms; especially the feast of the passover, which it is thought is alluded to here.
It is a common notion of the Jews , that the slaughter of the Assyrian army was on the night of the passover; that it was in the night is certain, 2Ki 19:35 but that it was on the night of the passover is not certain; however, the songs sung on that night were not on this occasion, nor could this be sung so soon; and it will be at evening time that the latter day glory shall break out, and songs of joy be heard from the uttermost parts of the earth, Zec 14:7:as when one goeth with a pipe to come into the mountain of the Lord; the temple; it being usual for persons, that came from distant parts of the land to the temple to worship, to bring pipes along with them in their hands, and play upon them as they were travelling, to divert them, and the company that were with them; see Ps 42:4.
Jarchi thinks the allusion is to the bringing up of the first fruits to the temple at Jerusalem, which was preceded with a pipe, as appears from the Misnah :to the mighty One of Israel; or, "Rock of Israel" ; one of the names of the Messiah, 2Sa 23:3 to whom the song of praise and triumph shall be sung, in the latter day, by those that stand upon Mount Zion, with harps in their hands, having gotten the victory over the beast and his image, Re 14:1.
