Commentaries:
Jamieson, Fausset, and Brown
Take heed, etc.—that is, See that thou be quiet (not seeking Assyrian aid in a fit of panic).
tails—mere ends of firebrands, almost consumed themselves (about soon to fall before the Assyrians, Isaiah 7:8), therefore harmless.
smoking—as about to go out; not blazing.
son of Remaliah—Pekah, a usurper (II Kings 15:25). The Easterners express contempt by designating one, not by his own name, but by his father's, especially when the father is but little known (I Samuel 20:27, I Samuel 20:31).
