Gennee...did you possibly mean...
...Deut 23:2? As it is rendered in the NAB:
"No one whose testicles have been crushed or whose penis has been cut off, may be admitted into the community of the Lord."
Wow, what a gruesome verse! But I could see someone using it, gruesome as it is, to make an argument against transgendered persons. Is this the verse you meant?
