For the LORD shall rise up as [in] mount Perazim, he shall be wroth as [in] the valley of Gibeon, that he may do his work, his strange work; and bring to pass his act, his strange act.
Berean Study Bible (BSB) - Isaiah 28:21 >For the LORD will rise up as at Mount Perazim. He will rouse Himself as in the Valley of Gibeon, to do His work, His strange work, and to perform His task, His disturbing task.
