I Have Refined You in the Furnace of Affliction
Isaiah 48:1-22
1 “Hear this, house of Jacob, you who are called by the name of Israel, and have come out of the waters of Judah. You swear by Yahweh’s name, and make mention of the God of Israel, but not in truth, nor in righteousness— · WEB
God explains why he told them in advance, and says what their peace would have been like if they had listened.
You swear by Yahweh's name, and make mention of the God of Israel, but not in truth, nor in righteousness Isaiah 48:1.
The chapter is addressed to people whose religion is entirely in order and whose hearts are not, and it is the last word to the exiles before the Servant Songs begin.
I have declared the former things from of old... I did them suddenly, and they happened Isaiah 48:3.
Because I knew that you are obstinate, and your neck is an iron sinew, and your brow bronze; therefore I have declared it to you from of old Isaiah 48:4–5.
The reason for prophecy, and it is unflattering. Predictions were given in advance because these particular people would otherwise have credited the outcome to something else — lest you should say, "My idol has done them". The whole apparatus of foretelling exists to close off an excuse.
A stiff neck is one that will not turn to look; a bronze forehead is one that pushes through.
For my name's sake, I will defer my anger, and for my praise, I hold it back for you so that I don't cut you off Isaiah 48:9.
Behold, I have refined you, but not as silver. I have chosen you in the furnace of affliction Isaiah 48:10.
The qualification is the most interesting phrase in the chapter and its sense is disputed. Silver is refined until it is pure, and the process is repeated until nothing but silver remains. Whatever was done here was not that — either because the fire was reduced, or because the yield would not have justified it. Either reading concedes that the refining was moderated.
And the choosing happened in the furnace, not before it.
For my own sake, for my own sake, I will do it; for how would my name be profaned? I will not give my glory to another Isaiah 48:11.
Said twice, and it removes the last possible ground for supposing the deliverance was earned.
Now the Lord Yahweh has sent me with his Spirit Isaiah 48:16.
A sentence that breaks the pattern. The speaker through the chapter has been God; here someone says he has been sent, by the Lord Yahweh, with the Spirit. Three parties in one clause, and the book offers no explanation.
Oh that you had listened to my commandments! Then your peace would have been like a river and your righteousness like the waves of the sea Isaiah 48:18.
The most wistful verse in the book. Two images of something inexhaustible — a river that does not stop and surf that keeps arriving — and both are stated as what would have happened. It is God describing an alternative history, and grieving over it.
Leave Babylon! Flee from the Chaldeans! With the sound of joyful shouting announce this Isaiah 48:20.
"There is no peace," says Yahweh, "for the wicked" Isaiah 48:22.
The line closes this section and recurs to close the next Isaiah 57:21, dividing the last twenty-seven chapters into three.
