Cite the scripture rather than merely going on about it, please. Marking the body is frowned upon and even forbidden in the OT. Maintaining an appearance of propriety in the eyes of your people is admonished in Romans as far as NT, to name a few.
So, have at it. It seems as if this is a topic that carries a great deal of emotional weight for you. I’m sure, then, that you’ll be pleased to provide the scriptural rationale.
Genesis chapter 24 verse 22.
Ring a bell.
Grab yourself a concordance, and a dictionary of biblical Hebrew.
Following a vision from God, gifts were sent for a young lady who turned out to be Rebekah.
And if you cross reference the words in Hebrew with an archaeological dictionary, the ring in verse 22 was either an eyebrow ring or a nose ring.
That was the culture of the day and that is the accurate parsing of the term. From the weight an eyebrow ring is highly unlikely.
For the dead...
Leviticus 19:28
"'Do not cut your bodies for the dead or put tattoo marks on yourselves.
