The Spirit of God identifies Edom with Babylon. (See Ps. 137:7 -8.) "Remember, My LORD, The Children of Edom, in the day of Jerusalem, who said Raze it, raze it," (i.e. make it bare destroy the Temple, like the Romans did, even to the foundation thereof."Here we see, without any possibility of mistake, that Edom is Babylon , and all sacred and profane history confirms it's Babylon. ( Isaiah 23:13,)
 "Behold the land of the Chaldeans, this people was not till the Assyrian founded it for them. The capital of Chaldea was Babylon. The Assyrian empire embraced the country on both sides of the Tigris. Babel, was founded by Nimrod. The Assyrians descended from Taurus, and the Caucasus conquered and destroyed Jerusalem, together with Syria; and these, with Phoenicia, became The Roman Empire, and was called Chaldea; as it was in the time of Jesus under Tiberius Caesar. (Luke 3:1.)
