Jeremiah 25:11-12
11 This whole land will become a desolate ruin, and these nations will serve the king of Babylon for 70 years.(A)
12 When the 70 years are completed, I will punish the king of Babylon and that nation’—this is the Lord’s declaration—‘the land of the Chaldeans, for their guilt, and I will make it a ruin forever.(B)
