The Lord announced that because they had not obeyed Him, He would bring Nebuchadnezzar down from the north, and destroy them and their neighbor nations with an awful, everlasting devastation. Nebuchadnezzar was the Lord"s servant in the same sense Cyrus was (cf. Isaiah 44:28 to Isaiah 45:1); he served the Lord by carrying out His will, for the most part unwittingly (cf. Jeremiah 27:6; Jeremiah 43:10; Acts 2:23). Since God"s people would not listen to His servants the prophets ( Jeremiah 25:4), the Lord would send another type of servant to get their attention (cf. Isaiah 28:11). [source][source][source]
