Isaiah 28:21-23

New International Version - UK

²¹ The Lord will rise up as he did at Mount Perazim,
    he will rouse himself as in the Valley of Gibeon –
to do his work, his strange work,
    and perform his task, his alien task.
²² Now stop your mocking,
    or your chains will become heavier;
the Lord, the Lord Almighty, has told me
    of the destruction decreed against the whole land.
