“Speake vnto the children of Israel, saying, If a woman haue conceiued seed, and borne a man child, then she shal be vncleane seuen dayes: according to the dayes of the separation for her infirmitie shall she be vncleane.”
1611 King James Version (KJV)
12:2 Seven days - Not for any filthiness which was either in the conception, or in bringing forth, but to signify the universal and deep pollution of man's nature, even from the birth, and from the conception. Seven days or thereabouts, nature is employed in the purgation of most women. Her infirmity - Her monthly infirmity. And it may note an agreement therewith not only in the time, #Lev 15:19|, but in the degree of uncleanness.
