Woah, more extreme rules… I’m having Leviticus flashbacks. Any worship of other Gods in Canaan is to be punished by stoning, burning, complete erasure from existence.
We find it extreme today, they found it extreme then. Israel did worship other Gods, they never did love the lord with all their heart. They never stoned people for it as far as I know, or at least they very often didn’t.
Jesus put it this way: the wages of sin is death.
So after the shock of the violence, there is also the sadness that of course it didn’t work, it exists to show us it didn’t work, it still doesn’t. We fail and fail to love our creator.
