Esias 14:24 In-Context

22 And I will rise up against them, saith the Lord of hosts, and I will destroy their name, and remnant, and seed: thus saith the Lord.
23 And I will make the region of Babylon desert, so that hedgehogs shall dwell , and it shall come to nothing: and I will make it a pit of clay for destruction.
24 Thus saith the Lord of hosts, As I have said, so it shall be: and as I have purposed, so shall remain:
25 to destroy the Assyrians upon my land, and upon my mountains: and they shall be for trampling; and their yoke shall be taken away from them, and their glory shall be taken away from their shoulders.
26 This is the purpose which the Lord has purposed upon the whole earth: and this the hand that is uplifted against all the nations.
