All are conceived and born in sin (Psalm 51:5) for, if the root be impure, so is the branch.
It is only by Christ, the great sin offering, that the corruption of the child nature is done away.
1 And the LORD spake unto Moses, saying,
2 Speak unto the children of Israel, saying, If a woman have conceived seed, and 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.
3 And in the eighth day the flesh of his foreskin shall be circumcised.
4 And she shall then continue in the blood of her purifying three and thirty days; she shall touch no hallowed thing, nor come into the sanctuary, until the days of her purifying be fulfilled.
5 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.
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:
7 Who shall offer it before the LORD, and make an atonement for her; and she shall be cleansed from the issue of her blood. This is the law for her that hath born a male or a female.
8 And if she be not able to bring a lamb, then she shall bring two turtles, or two young pigeons; the one for the burnt offering, and the other for a sin offering: and the priest shall make an atonement for her, and she shall be clean.

Leviticus 12:1-8 – Purification after Child-Bearing
The birth of a boy involved seven days’ ceremonial defilement; of a girl, fourteen. Not the child, but the mother, was adjudged to be unclean, securing her a period of retirement and rest. The gracious gradation in the sacrifices made it possible for the poorest to obey, and it is a memorable fact that the mother of our Lord brought two pigeons or doves—meet emblems of her gentle nature—when she presented her babe in the Temple. See Luke 2:24. Our Lord became poor, that through His poverty we might be eternally enriched. In the light of this ceremonial, we are led back to Psalm 51:5, which we must personally and sadly ponder.
The initial rite of the Hebrew religion stood for separation. The parent taught the child to remember that he belonged to a separated race. It was impossible for him to consort with those who were aliens from the commonwealth of Israel. We all need to undergo the circumcision of Christ, which consists in putting away the sins of the flesh, and ceasing to trust in our own energy. See Colossians 2:11-12. —Through the Bible Day by Day
Leviticus 12:8 – Two young pigeons.
These were the offerings of the poor, of those whose means did not suffice to buy a lamb. All these offerings pointed to the one great Sacrifice which was to be offered on Calvary.
The blood of Christ is within the reach of the poorest and feeblest.—None can say that it is beyond them, that they cannot afford to procure it, that they are too poor. To the poor the Gospel is preached. The Divine call is to those who have no money. Salvation is to Him that worketh not, but believeth on Him that justifieth the ungodly. “The word is nigh thee” (Romans 10:8).
The faith that apprehends but a part of the Savior’s work saves.—The pigeon may stand for the meager apprehension of Christ that is the portion of the faltering and timid; but it saves equally with that fuller conception of his saving work, which might be compared to the bullock of the priest. The question is not as to the quantity but the object of faith. Is it fixed on Jesus? All faith directed to Him cannot but be genuine. It may but touch His garment’s hem, yet it saves.
The beneficence of God’s law.—What tender touches there are through this strong ancient code! There is such a one here, framed partly in anticipation of the mother of our Lord, who gladly availed herself of its provision. What a glimpse into our Masters humiliation! He owned the cattle on a thousand hills, yet He so emptied Himself that His parents were compelled to bring the poorest offering the law allowed. He stooped that we might rise; emptied Himself that we might be full; became poor that we might be made rich; was made human that we might be made Divine. —Our Daily Homily
