Sennacherib invades Judah, ver. 1. He sends Rabshakeh, who by his blasphemous persuasions tempts Hezekiah to despair, and the people to revolt, ver. 2-22. The history related here, and in the three following chapters, is, almost in the same words contained 2 Kings 18, 19, 20. It is inserted here, to explain and confirm some of the foregoing predictions. It may seem to have first been written by this prophet, and from him taken into the book of Kings, to compleat that history.
