Isaiah 30:8

The Lord commanded Isaiah to write a public record on a table and a private one on a scroll, two enduring witnesses against His people’s lack of trust in Him. The public record was for His people then to learn from, and the private one was for later generations. Other ancient Near Eastern nations recorded uniformly positive and complementary things about themselves, in contrast to what Isaiah wrote here about Judah. The content of what he wrote is unclear, but it was probably this oracle in some form.
