The tattoo thing in the mosaic law times was all about religious tattoos of other gods,
Also if we were under the mosaic law there's lots of other things we should be doing, ie washing up to the elbows, observing the sabbath..
It's still considered to be a conscience matter.. but you certainly wouldnt be considered 'spiritual' if it became known you had one done, and if you were a brother your privileges would be removed..
I had my first tattoo aged 30 when I was still a good dub. Now I have 4, my favourite one being on my lower back, I used to love to bend over and search through my bag and flash it..
Guess we had to make our own fun at the meetings!!
