There are 7427 blatant absurdities in the bible. Among them:
If you get a rise from nonsense, look no further than the holy bible, a book so good that a few idiots decided to violate the US Constitution by displaying it in the halls of public buildings.
Exodus 28:34 A golden bell and a pomegranate, a golden bell and a pomegranate, upon the hem of the robe round about.35 And it shall be upon Aaron to minister: and his sound shall be heard when he goeth in unto the holy place before the LORD, and when he cometh out, that he die not.
You may not pray like the Pharisees, Sadducees, and Essenes, and show off while you worship; but entering the holy place without wearing bells can result in death. Try to reconcile that with Matthew 6:5 And when thou prayest, thou shalt not be as the hypocrites are: for they love to pray standing in the synagogues and in the corners of the streets, that they may be seen of men. Verily I say unto you, They have their reward.
So God/Jesus thinks wearing a cow bell around your neck, in church, will not attract attention.
