The beauty of Israel is slain upon thy high places: how are the mighty fallen!
The beauty of Israel - literally, the gazelle or antelope of Israel (cf. 2 Samuel 2:18; 1 Chronicles 12:8; Song of Solomon 2:7; Song of Solomon 3:5). In Eastern countries that animal is the chosen type of beauty and symmetrical elegance of form.
How are the mighty fallen! This forms the chorus.
