Leviticus 22:4-6

Tyndale(i) 4 None of the seed of Aaron that is a leper or that hath a runnynge sore shall eate of the halowed thinges vntill he be cleane. And whosoeuer twytcheth any vncleane soule or man whose seed runneth fro him by nyghte, 5 or whosoeuer twitcheth any worme that is vncleane to him or man that is vncleane to him what soeuer vnclennesse he hath: 6 the same soule that hath twyched any soch thynge shalbe vncleane vntill euen and shall not eate of the halowed thynges vntill he haue wasshed his flesh with water.
