What does Isaiah 10:27 mean?
This judgment through the Assyrians (Isaiah 10:5–7) will end. Those who survive the Lord's anger through the weapon of the Assyrian nation are promised that His wrath will end. He will direct His anger, instead, at the Assyrians, using His supernatural power once more to save Israel from foreign oppression (Isaiah 10:25).The Lord now promises that the Assyrian oppression will be removed. A "yoke" is a connecting tool put on the shoulders of livestock so they can work. It is a common symbol of effort or even slavery in Scripture (1 Kings 12:4; Isaiah 9:4; Matthew 11:29–30). Then the God notes that the yoke will be broken "because of the fat." Commentators are not certain of the meaning of this phrase. It may suggest that Israel will become so prosperous, that they will be like an ox that gets fat and becomes too big for its yoke, breaking free in the process.
The promise is clear. The Lord God who used the Assyrians to bring destruction to Israel will soon bring destruction to the Assyrians.
