Ezekiel 36:18-19

“Because of this I poured out my fury on them, for the blood which they had poured out on the land, and because they had defiled it with idols, and I scattered them among the nations, and they were dispersed through the countries. According to their ways and according to their doings I judged them.”

The consequence of their behaviour was that God expelled them from the land so that it could be purified. Stress is especially laid here on two things, violence and idolatry. They shed blood wrongly, defiling the land, and they introduced idols which were an abomination to God. And He stresses that their judgment was based on their behaviour. They had brought what happened on themselves.
