Son of man, set thy face toward the mountains of Israel, and prophesy against them,
Set thy face toward ... mountains of Israel - i:e., of Palestine in general. The mountains are addressed by personification; implying that the Israelites themselves are incurable, and unworthy of anymore appeals; so the prophet sent to Jeroboam did not deign to address the king, but addressed the altar (1 Kings 13:2). The mountains are specified, as being the scene of Jewish idolatries on "the high places" (Ezekiel 6:3).
