Albert Barnes Commentary Isaiah 28:22

"Now therefore be ye not scoffers, lest your bonds be made strong; for a decree of destruction have I heard from the Lord, Jehovah of hosts, upon the whole earth." — Isaiah 28:22 (ASV)

Now therefore - In view of the certain judgment which God will bring upon you.

Be ye not mockers - This was the prevailing sin (Isaiah 28:9–14), and on account of this sin in part, the judgment of God was about to come upon the guilty nation.

Lest your bands be made strong - Lest your confinement should be more severe and protracted. God would punish them according to their sins, and if they now ceased to mock and deride him, it would greatly mitigate the severity of their punishment .

For I have heard ... - I, the prophet, have heard Yahweh of hosts threaten a consumption.

A consumption ... - (see this phrase explained in the note at Isaiah 10:23)

Upon the whole earth - The whole land of Judea (see the note at Isaiah 24:1).
