Verse 1From uncleanness contracted by the touching or eating of external things, he now comes to that uncleanness which ariseth from ourselves. Verse 2Seven 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. Verse 4In the blood of her purifying - In her polluted and separated estate; for the word blood or bloods signifies both guilt, and uncleanness, as here and elsewhere. And it is called the blood of her purifying, because by the expulsion or purgation of that blood, which is done by degrees, she is purified. No hallowed thing - She shall not eat any part of the peace - offerings which she or her husband offered, which otherwise she might have done; and, if she be a priest's wife, she shall not eat any of the tythes or first fruits, or part of the hallowed meats, which at other times she together with her husband might eat. Verse 5Threescore and six days - The time in both particulars is double to the former, not so much from natural causes, as to put an honour upon the sacrament of circumcision, which being administered to the males, did put an end to that pollution sooner than otherwise had been. Verse 6For a son or a daughter - For the birth of a son, or of a daughter: but the purification was for herself, as appears from the following verses. A sin - offering - Because of her ceremonial uncleanness, which required a ceremonial expiation. Verse 8The morality of this law obliges women who have received mercies from God in child - bearing, with all thankfulness to acknowledge his goodness to them, owning themselves unworthy of it, and (which is the best purification) to continue in faith, and love, and holiness, with sobriety.
