6 And when the days of her purifying are fulfilled, for a son, or for a daughter, she shall bring a lamb of the first  year for a burnt offering, and a young pigeon, or a turtledove, for a sin offering, unto the door of the tabernacle of the congregation, unto the priest:
6 " 'When the days of her purification for a son or daughter are over, she is to bring to the priest at the entrance to the tent of meeting a year-old lamb for a burnt offering and a young pigeon or a dove for a sin offering.
6 "'And when the days of her purifying are completed, whether for a son or for a daughter, she shall bring to the priest at the entrance of the tent of meeting a lamb a year old for a burnt offering, and a pigeon or a turtledove for a sin offering,
6 "When the days for her purification for either a boy or a girl are complete, she will bring a yearling lamb for a Whole-Burnt-Offering and a pigeon or dove for an Absolution-Offering to the priest at the entrance of the Tent of Meeting.
6 'When the days of her purification are fulfilled, whether for a son or a daughter, she shall bring to the priest a lamb of the first year as a burnt offering, and a young pigeon or a turtledove as a sin offering, to the door of the tabernacle of meeting.
6 "When the time of purification is completed for either a son or a daughter, the woman must bring a one-year-old lamb for a burnt offering and a young pigeon or turtledove for a purification offering. She must bring her offerings to the priest at the entrance of the Tabernacle.
Matthew Henry's Commentary on Leviticus 12:6
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," Genesis 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.
