How to tell when someone is unethical or immoral? In the time in the desert, when someone acted this way, their very skin, clothing, and even walls of their spaces, would discolor.
There are ten causes for these markings – tazria – that the rabbis mention – from bottom right going up and around – worshiping idols, sexual immoralities, murder, mocking the Jewish people, stealing, disregarding Torah precepts, conceit, lashon hara evil speech about others, the evil eye, and swearing falsely. With the negative lying from political schemers today, maybe tazria evidence should return!
