Wherefore thus saith the Lord: these vile wretches having now done speaking, God begins to speak; and because they had thus slighted the prophet, and God speaking by him, (as in the next words, Because ye speak this word,) here tells them what he will do; or rather, turns himself abruptly to the prophet, as men usually do in a passion. The Lord God of hosts; he makes his majesty and power known, to clothe his words with the greater terror. Because ye speak this word, viz. at the rate they discoursed in the former verse. It shall devour them, i.e. it shall take place suddenly, and irresistibly, and fiercely, as fire is wont to take in dry wood, to their utter ruin and overthrow, Psalms 83:14,15 Isa 9:18,19. They shall be but fuel to my wrath, which shall be executed by the Chaldean army, that shall consume and eat them up like fire; they shall find my words to be more than wind.
