Most people who say the bible should be taken literal would themselves be dead if the bible was taken laterally
Actually the Bible verse says we can handle serpents safely, but doesn't tell people to do it.
The New Testament DOES tell women to wear veils, stay at home, obey their husbands, don't talk in church, and have children.
The Old Testament says to stone to death anyone who picks up anything on Saturday, kids who talk back, that men can sell their daughters into slavery, etc.
They do it as a way of showing faith.
