Observe this commandment and do it, my son, that thou mayst be upright in all thy deeds.
And at all times be clean in thy body, and wash thyself with water before thou approachest to offer on the altar, and wash thy hands and thy feet before thou drawest near to the altar;
and when thou art done sacrificing, wash again thy hands and thy feet. And let no blood appear upon you nor upon your clothes;
