Isaiah 26:1,2

Reader! do not fail to observe how the prophet continually harps upon that day, that glorious clay, the gospel day, when the Lord will bring again Zion. And though some have thought that the deliverance of the Church out of Babylon might well call forth this song, of praise; yet even then, every child of God, even Israel thus delivered, could not but celebrate that temporal salvation as typical of a spiritual and eternal salvation by the Lord Jesus Christ. The deliverance of the Church from Egypt, was a type; and consequently the deliverance from Babylon is the same. And as this song was to be sung in Judah; was it not as a representation of the Church of Jesus? See those scriptures, Jeremiah 23:5; Hebrews 8:8; Isaiah 60:18.
