The Lord is judge and discipline he loved one.

Ezekiel 35:1-15
Face against Mount Seir, God will make Seir a perpetual永久 desolation and a waste.
Because you did not hate bloodshed, there blood shall pursue you.
As you rejoiced over the inheritance of the house of Israel, because it was desolate, so I will deal with you; you shall be desolate, Mount Seir, and all Edom, all of it. Then they will know that I am the Lord.
Why?
God let the enemy of Israel know he is the Lord.
All nations did against Israel when they were in calamity, so the anger of God comes on them.
Rejoice with who is happy, but not with the people under desolation.
Judge is the role of the Lord, we hate the evildoer but we should have mercy to everyone, pity for the one who doesn't know the truth and the Lord.
Edom killed the escaped people of Israel when their country was destroyed by Babylonian.
Mountain Seir is the nation of Edom.
Perpetual desolation is very severe punishment.
How?
Plant righteous seed gets the righteousness, plant hate seed gets desolation. The Lord is judge and discipline he loved one.
