In Leviticus 22:1-9, God explains that priests who have been made unclean are not allowed to eat the holy food (sacrificial bread and meat), until they are made clean by bathing in water and waiting until sundown. The bible lists numerous things that can make a priest unclean, most of which have been stated earlier: having leprosy, a discharge of pus, touching the dead, ejaculating, touching a non-kosher animal, or eating an already dead animal. Most of the list is together, but part of it is sloppily unattached from the rest.
So where does Quazar get off (ha!) making his crotch-rot comment? Well, here God is saying that anyone with a “running issue” (the NIV says, “bodily discharge”) is unclean and cannot eat the holy food. However, back in Leviticus 21:20-22, God said that priests covered in scabs may still eat his sacrificial bread (though someone else must present it). So take a note folks, gonorrhea is unclean, herpes is not!
By the way, any priests who eats sacrificial food in an unclean state is subject to death—what else is new, right?
