Son of man, set thy face against mount Seir, and prophesy against it,
Mount Seir — The Edomites, who inhabited it.
 Because thou hast had a perpetual hatred, and hast shed the blood of the children of Israel by the force of the sword in the time of their calamity, in the time that their iniquity had an end:
Their iniquity — When their iniquity was punished on them, which brought them to final ruin.
 Therefore, as I live, saith the Lord GOD, I will prepare thee unto blood, and blood shall pursue thee: sith thou hast not hated blood, even blood shall pursue thee.
And blood — Thy guilt, and my just revenge of innocent blood.
Hast not hated — Thou hast loved, rather than hated, blood-shed; therefore vengeance for it follows thee.
 Thus will I make mount Seir most desolate, and cut off from it him that passeth out and him that returneth.
That passeth out — All travellers that go to or from Edom.
 I will make thee perpetual desolations, and thy cities shall not return: and ye shall know that I am the LORD.
Return — To their former glory.
 Because thou hast said, These two nations and these two countries shall be mine, and we will possess it; whereas the LORD was there:
Though — Though God was with Israel.
 Therefore, as I live, saith the Lord GOD, I will even do according to thine anger, and according to thine envy which thou hast used out of thy hatred against them; and I will make myself known among them, when I have judged thee.
Judged — Punished thee.
 Thus saith the Lord GOD; When the whole earth rejoiceth, I will make thee desolate.
The whole earth — The inhabitants of all the countries round about thee.
Rejoiceth — Is in peace and plenty.
