Esias 28:21

21 The Lord shall rise up as a mountain of ungodly , and shall be in the valley of Gabaon; he shall perform his works with wrath, a work of bitterness, and his wrath shall deal strangely, and his destruction shall be strange.

Esias 28:21 In-Context

19 Whenever it shall pass by, it shall take you; morning by morning it shall pass by in the day, and in the night there shall be an evil hope. Learn to hear,
20 ye that are distressed; we cannot fight, but we are ourselves too weak for you to be gathered.
21 The Lord shall rise up as a mountain of ungodly , and shall be in the valley of Gabaon; he shall perform his works with wrath, a work of bitterness, and his wrath shall deal strangely, and his destruction shall be strange.
22 Therefore do not ye rejoice, neither let your bands be made strong; for I have heard of works finished and cut short by the Lord of hosts, which he will execute upon all the earth.
23 Hearken, and hear my voice; attend, and hear my words.
