For it is the day of the LORD'S vengeance, and the year of recompense for the controversy of Zion.
Read Chapter 34

Recompenses. When the persecutors of Sion, that is, of the Church, shall receive their reward. (Challoner)
The Idumeans had frequently shown their ill-will towards the Jews, 2 Paralipomenon xxviii. 17., and Amos i. 11. (Calmet)
Sion shall perish as the wicked in hell shall be tormented. (Worthington)
It [sacred Scripture] has a dreadful appearance when, describing hell, it says, “The day of the vengeance of the Lord, the year of recompense of the judgment of Zion. And the streams thereof shall be turned into pitch, and the ground thereof into brimstone: and the land thereof shall become burning pitch. Night and day it shall not be quenched … forever.” - "Homilies on Ezekiel 1.6.18"
