It makes perfect sense. Children are REAL WEALTH! (re-translate for the kiddies) "No Mr Satan I will not destroy myself because I don't have none of your nasty little imaginary dollars to make myself grand with".making more babies because you are poor makes about as sense as spending more money when you don't have any.
All the poor have to do to stop being poor is to TAKE the land from the "rich", to take "gods" given wealth as their own.
Land is wealth, children are wealth, cattle are wealth, numbers in a bank account are a fake wealth used to raise the greedy on the platform of their own pride. Go read a bible, I never have.
