After the wedding ceremony, many Orthodox Jews believe that a woman should only show her hair to her husband. According to the Mishnah in Ketuboth (7:6), hair covering is not an obligation of biblical origin. It discusses behaviors that are grounds for divorce such as, "appearing in public with loose hair, weaving in the marketplace, and talking to any man" and calls these violations of Dat Yehudit, which means Jewish rule, as opposed to Dat Moshe, Mosaic rule. However, the Talmud on this Mishna explains that if the hair is completely uncovered in public, this would indeed be a violation of "Dat Moshe", and the Mishna is referring to one who cover her hair with a netlike covering where hair is visible through the holes, as in this case the Biblical requirement is met, but not the "Dat Yehudit".. This categorization suggests that hair covering is not an absolute obligation originating from Moses at Sinai, but rather is a standard of modesty that was defined by the Jewish community. In Berakhot 24a), the rabbis define hair as sexually erotic (ervah), and prohibit men from praying in sight of a woman's hair. The rabbis base this estimation on a biblical verse: "Your hair is like a flock of goats" (Song of Songs 4:1), suggesting that this praise reflects the sensual nature of hair.
