“But if she bear a maid child, then she shall be unclean two weeks, as in her separation: and she shall continue in the blood of her purifying threescore and six days.”
King James Version (KJV)
Matthew Henry's Concise Commentary
12:1-8 Ceremonial purification. - After the laws concerning clean and unclean food, come the laws concerning clean and unclean persons. Man imparts his depraved nature to his offspring, so that, excepting as the atonement of Christ and the sanctification of the Spirit prevent, the original blessing, Increase and multiply, Ge 1:28, is become to the fallen race a direful curse, and communicates sin and misery. Let those women who have received mercy from God in child-bearing, with all thankfulness own God's goodness to them; and this shall please the Lord better than sacrifices.
“What? know ye not that he which is joined to an harlot is one body? for two, saith he, shall be one flesh.”
