I recently passed along my notes on the book of Isaiah to someone and, so, I thought I might post a PDF document of the notes I put together about 4 years ago from when I taught Old Testament studies at a ministry-theology college. Isaiah’s words are long and, thus, this document is 70 pages. But feel free to download and utilise if you would like. I, of course, mention many other resources to us.
