Behold, I will send a blast upon him— Behold, I will put a spirit [of fear] into him, when he shall hear, &c. Vitringa. See chap. Isaiah 31:8-9 whence it clearly follows, that the interpretation here given is right, and that the prophet here refers to the fears of Sennacherib upon the report of Tirhakah's invasion, and not a pestilential blast, as our version would lead one to think.
