Deuteronomy 22:23-24

If a young virgin has given her word to be married to a man, and another man meeting her in the town, has connection with her; Then you are to take the two of them to the doorway of the town, and have them stoned to death; the young virgin, because she gave no cry for help, though it was in the town, and the man, because he has put shame on his neighbour's wife: so you are to put away evil from among you.
