A running sore.
Blind, or broken, or maimed, or having a WEN, or scurvy, or scabbed, ye shall not offer these unto the LORD, nor make an offering by fire of them upon the altar unto the LORD. ( Leviticus 22:22 )
Only in Leviticus 22:22, "maimed" or "having a wen (margin "sores"), or scurvy," for (yabbal), "running," hence, "a suppurating sore" (compare the Revised Version margin). A "wen" is a non-inflamed indolent tumor, and so "wen" is about as far as possible from the meaning of the Hebrew.
