Parallel
Isaiah 28:21
Brenton's English Septuagint · Berean Standard Bible
The Lord shall rise up as a mountain of ungodly [men], and shall be in the valley of Gabaon; he shall perform his works with wrath, [even] a work of bitterness, and his wrath shall deal strangely, and his destruction shall be strange.
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.
