Isaiah 7:4

and say unto him, who was probably engaged in having the fortifications strengthened, Take heed and be quiet, perfectly unconcerned and without worry; fear not, neither be faint-hearted, literally, "and thy heart, not be it soft with despondency," for the two tails of these smoking fire-brands, burned-out and quenched stumps of torches, for the fierce anger of Rezin with Syria, with his whole great army, and of the son of Remaliah, as Pekah, king of Israel, is contemptuously called. All the enemies of God and of His Church are always helpless before His almighty power.
