Preserve the oracles of Isaiah (Isa 30:8-30:8)

“Go now!

Write it before them on a tablet!

Inscribe it in a book!

Thus it may be for the time to come.

Let this be a witness forever!”

Isaiah wanted them to preserve his oracles. He wanted them to write these oracles on a tablet. Then they were to keep them on a scroll in some kind of book. Thus they would become a lasting witness about things to come in the future. Apparently, this was done.
