Cast away from you all the transgressions that you have committed, and make
yourselves a new heart and a new spirit! Why will you die, O house of Israel?

He declared to them the following...
“Therefore, you Israelites, I will judge each of you according to your own ways,
declares the Sovereign Lord. Repent! Turn away from all your offenses then sin
will not be your downfall.' Ezekiel 18:30
God was requiring of them something that required them to make up their own minds. (volition)
