Written on the back
In Revelation 5:1, the book being written on the back signifies the Word in its general sense. (Apocalypse Revealed 256)
In Ezekiel 8:16, this signifies denial of the Lord God, one of the abominations of the decadent Jerusalem. (Apocalypse Explained 401[32])
Isaiah 45:13
13
I have raised him up in righteousness, and I will make straight all his ways. He shall build my city, and he shall let my exiles go free, not for price nor reward," says Yahweh of Armies.
