born a man child: then she shall be unclean seven days; according to the days of the separation for her infirmity shall she be unclean.
And in the eighth day the flesh of his foreskin shall be circumcised.
Circumcision refers to having a pure heart separated unto God. Deuteronomy 10:16 compares circumcision to the foreskin of the heart, and be no longer stiff-necked. This is the number 8 again is echoing to August reference, comparing to the 8th day circumcision after birth. The bride forsakes all else to follow Christ. Being completely separated unto God is where the bride is immune to the corruptible seed, and the divine seed imparted into her transforms her from corruptible to incorruptible.
Genesis 7:2-3 – There were 5 times mentioning of “male and female”: 2 Of every clean beast thou shalt take to thee by sevens, the male and his female: and of beasts that are not clean by two, the male and his female.
3 Of fowls also of the air by sevens, the male and the female; to keep seed alive upon the face of all the earth.
9 There went in two and two unto Noah into the ark, the male and the female, as God had commanded Noah.
16 And they that went in, went in male and female of all flesh, as God had commanded him: and the Lord shut him in.
