And the word of Jehovah came unto me, saying,
Son of man, set thy face toward the mountains of Israel, and prophesy against them,
and say, Mountains of Israel, hear the word of the Lord Jehovah: thus saith the Lord Jehovah to the mountains and to the hills, to the water-courses and to the valleys: Behold, I, [even] I, do bring a sword upon you, and will destroy your high places.
