Edom is another name for Esau, Jacob's brother. The Greek form of the word Edom is Idumea. Those who settled in Edom were close kin to the residents of Judah. Sidney B. Sperry said: "The history of the relations between Israel and Edom is from the beginning fraught with envy and hate. In Gen. 36:1 we have the following statement: 'Now these are the generations of Esau -- the same is Edom.' This recalls to us the struggle for supremacy from birth, or even before, of Esau and his younger brother Jacob (Israel) ... Esau sold his birthright to his brother for a mess of pottage and finally the holy patriarchal inheritance also. Esau, it will be recalled, married among the Canaanites, which fact was a great trial to his parents." (The Voice of Israel's Prophets, pp. 318-19)
Because of their wickedness and lasting hatred for Israel, Edom, like Babylon, became a symbol of the world (see D&C 1:36).

The "house of Jacob shall be a fire, and the house of Joseph a flame ... and they shall kindle in them [Esau], and devour them; and there shall not be any remaining of the house of Esau" (v. 18). Eventually, "saviors shall come up on mount Zion to judge the mount of Esau; and the kingdom shall be the Lord's" (v. 21).
