Isaiah 14:24
24The LORD of Armies has sworn, saying, “Surely, as I have thought, so shall it happen; and as I have purposed, so shall it stand:
Wesley: Saying—this verse does not only concern Babylon’s destruction, but also the overthrow of Sennacherib and the Assyrian host, which was a pledge of the destruction of the city and empire of Babylon. As I have thought, so shall it happen; as I have purposed, so shall it stand. The LORD of Armies has sworn.
The sworn purpose is sure. Sennacherib’s host is Wesley’s pledge. The oath stands in the land; it does not erase the armies he uses as means.
Calvin: for more full confirmation an oath was necessary. There is nothing of which it is more difficult to convince us than that wicked men will immediately be ruined, when we see them flourishing. On this account he employs an oath. As I have thought, so shall it be.
What he has purposed shall stand. The oath is the Lord’s, over Assyria. The LORD of Armies has sworn.
