Defending. Contending.

Ben Maulis says:

But Mary kept all these things, and pondered [them] in her heart…. And when the days of her purification according to the law of Moses were accomplished, they brought [Jesus] to Jerusalem, to present [him] to the Lord; (As it is written in the law of the Lord, Every male that openeth the womb shall be called holy to the Lord;) And to offer a sacrifice according to that which is said in the law of the Lord, A pair of turtledoves, or two young pigeons. –from Luke

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: 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. 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. –from Leviticus
