Can you tell me where in the Bible the most blatant case of ual harment is?

Lot and the angels in Soddom and Ghormoorah. Lot gave shelter to two men who were strangers to him. The mob came to his house demanding the strangers be let out so the mob could have their evil ual ways with them. Lot offered the mob his two daughters instead, even though he did not know at the time the strangers were acutally angels.
