Why do you think that? Alacrity means brisk and cheerful readiness. I would think the opposite.If we are to be consistent in interpretation, in the story it is because they had seen God's miracles in Egypt and the wilderness, which convinced them that he was real, that they carried out the stoning, not because they were barbaric in themselves. We have to ask why God would tell them to do it.In context, the incident is an example of someone sinning defiantly, which is discussed in the previous paragraph of Numbers 31.
Well, there is no mention of those that stoned him taking a long time to do it, or that they did it reluctantly. However, I'm quite happy to take back the word 'alacrity' with pleasure. It doesn't suggest the opposite however and it still doesn't change or excuse the deed one iota though.
You can ask whatever you like. It is still barbaric and reflects badly on the OT God.
Incidentally, in your previous post, your last paragraph said this:
Nowadays we have what I have recently heard described as an economic surplus. This enables us to lock up murderers in prison, so avoiding the need for capital punishment. Without that, it would be necessary to punish murder in the most efficient way possible. Given that some other things, such as you have listed, are damaging to society, and assuming no economic surplus, these too were made into capital offenses.
Apart from the obvious fact that it wasn't a case of murder for which the stick gatherer was being punished, you seem to be suggesting that any society which hasn't an 'economic surplus' would need to execute its murderers as being the way to go 'in the most efficient way possible'. You also seem to be suggesting that societies that do not have this 'economic surplus' should also execute their citizens in certain cases where no murder has been committed. God help us then, after we start to recover from the ravages of the Lockdown as execution, in your eyes, should be the order of the day. Frankly I'm appalled by your moral position, Spud. It certainly isn't mine. I'm not really surprised though, as you seem to be greatly influenced by this nasty OT God of yours.
