New Defender's Study Bible Notes
12:2 unclean seven days. There were no doubt certain health reasons for these seemingly stringent rules, but probably the main factor involved was to foster continued recognition that the sin of the first woman has been transmitted to all her descendants (note Psalm 51:5). All, therefore, are born to be sinners, so that even their mothers need purification. It is noteworthy that Mary, the mother of Jesus obeyed these laws for the purification of women after her divine Son was born. Even though He, by miraculous conception, was born free of sin, Mary recognized that she herself was not sinless and thus needed to obey the rules of purification (Luke 2:21-24).
