Did God prescribe circumcision for Abraham because the herders were docking with each other and spreading germ?
God didn’t prescribe it and it wasn’t done for cleanly reasons. Also circumcision back then was NOT what it is today. Back then they only took a small snip of foreskin so they kept most of the skin. Also circumcision isn’t cleaner and doesn’t prevent germs so either way your immature question has flaws.
