The high places also of Aven, the sin of Israel, will be destroyed. The thorn and the thistle will come up on their altars. They will tell the mountains, "Cover us!" and the hills, "Fall on us!"
"This sublime description of fear and distress our Lord had in view, Luke 23:30, which may be a reference, and not a quotation. However, the Septuagint, in the Codex Alexandrinus, has the same order of words as occurs in the evangelist. The parallelism makes the passages more beautiful than Revelation 6:16; and Isaiah 2:19 wants the animated dramatic form. That there is a reference to the caverns that abounded in the mountainous countries of Palestine, Isaiah 2:19." -Newcome.
