Thou therefore, son of man, prophesy, and smite thine hands together, and let the sword be doubled the third time, the sword of the slain: it is the sword of the great men that are slain, which entereth into their privy chambers. Let the sword be doubled the third time - The sword has been doubled, and it shall come the third time. Nebuchadnezzar came against Judea Thrice.
1. Against Jehoiakim.
2. Against Jeconiah.
3. Against Zedekiah.
The sword had already been doubled; it is to come now the third time, i.e., against Zedekiah.
The sword of the slain - חרב חללים chereb chalalim, "the sword of the soldiers," of the Chaldeans. So in the next clause, היא חרב חלל הגדול hi chereb chalal haggadol, "it is the sword of that great soldier," that eminent king and conqueror. This is the meaning of the word חלל chalal, that is so ill rendered in almost every place of its occurrence, in our Version. See Dr. Kennicott.
