Hesekiel 35:5

It was promised, in the foregoing chapter, that when the time to favour Zion, yea, the set time, should come, especially the time for sending the Messiah and setting up his kingdom in the world, God would cause the enemies of his church to cease and the blessings and comforts of the church to abound. This chapter enlarges upon the former promise, concerning the destruction of the enemies of the church; the next chapter upon the latter promise, the replenishing of the church with blessings. Mount Seir (that is, Edom) is the enemy prophesied against in this chapter, but fitly put here, as in the prophecy of Obadiah, for all the enemies of the church; for, as those all walked in the way of Cain that hated Abel, so those all walked in the way of Esau who hated Jacob, but over whom Jacob, by virtue of a particular blessing, was to have dominion. Now here we have, I. The sin charged upon the Edomites, and that was their spite and malice to Israel (Eze 35:5, Eze 35:10-13). II. The ruin threatened, that should come upon them for this sin. God will be against them (Eze 35:3) and then their country shall be laid waste (Eze 35:4), depopulated, and made quite desolate (Eze 35:6-9), and left so when other nations that had been wasted should recover themselves (Eze 35:14, Eze 35:15).

35:5-10 The eternal [or ancient] hatred of Edom for Israel went all the way back to their respective ancestors, Esau and Jacob (see Gen 25:19-34; 27:1-46; Num 20:14-21; 24:18; 2 Sam 8:13-14; 1 Kgs 11:14). Because of that enmity, the Edomites took advantage of the Babylonian destruction to butcher the Israelites when they were helpless. They wanted to wipe out the descendants of Jacob and seize the lands of Israel and Judah. The bloodbath they delighted to inflict on Israel would return on their own heads, as their people would be slaughtered by the sword. Their everlasting hatred would be punished: Their land would become desolate forever. This prophecy was fulfilled when the Edomites were displaced by a coalition of Arab tribes sometime during the 400s BC.
