Charles Ellicott Commentary Micah 3:5

"Thus saith Jehovah concerning the prophets that make my people to err; that bite with their teeth, and cry, Peace; and whoso putteth not into their mouths, they even prepare war against him:" — Micah 3:5 (ASV)

That bite with their teeth. —The concluding statement that the false prophets declare war against those who do not put into their mouth indicates the meaning of the former expression, namely, “they say peace to those who feed and bribe them.” The Hebrew word, nashak, which is rendered “bite,” is strictly applied to serpents, to an adder in the path, and is therefore especially appropriate to the false and lying nature of the prophets.
