Now therefore be ye not mockers, lest your bands be made strong: for I have heard from the Lord GOD of hosts a consumption, even determined upon the whole earth.
Be ye not mockers - a sin which they had committed (Isaiah 28:9-10).
Lest your bands be made strong - their Assyrian bondage (Isaiah 10:27). Judah was then tributary to Assyria. Or, 'lest your punishment be made still more severe.'
A consumption - destruction (Isaiah 10:22-23; Daniel 9:27).
