May it whirl on Joab’s head and on all his father’s house. May the house of Joab never be without someone with discharge or tza'arat, lame or one fallen by the sword or one who lacks food.”
“None of the offspring of Aaron who has tza'arat or has a discharge shall eat of the holy things until he is clean. Whoever touches anything that is unclean by the dead or a man whose seed discharges from him
“Or if he touches some human uncleanness, whatever his filth is by which he is unclean, though it is hidden from him, when he knows of it, then he will be guilty.
