The wife beating is part of the 7th century package of sensibilities. Jewish women were treated well as far back as you care to go.
I don’t know of any reference in the Bible that says beat your wife.
I couldnt find any doing a google search... only thing close is this... its pretty sickening really. Just like the muzzie scum would do...
Deuteronomy 22:20-1 If, however, the charge is true and no proof of the girl’s virginity can be found, she shall be brought to the door of her father’s house and there the men of her town shall stone her to death. She has done a disgraceful thing in Israel by being promiscuous while still in her father’s house.
