6-14. he shall bring his trespass offering unto the Lord for his sins which he hath sinned—A trespass offering differed from a sin offering in the following respects: that it was appointed for persons who had either done evil unwittingly, or were in doubt as to their own criminality; or felt themselves in such a special situation as required sacrifices of that kind [BROWN]. The trespass offering appointed in such cases was a female lamb or kid; if unable to make such an offering, he might bring a pair of turtledoves or two young pigeons—the one to be offered for a sin offering, the other for a burnt offering; or if even that was beyond his ability, the law would be satisfied with the tenth part of an ephah of fine flour without oil or frankincense.

     6-8. the days of her purifying—Though the occasion was of a festive character, yet the sacrifices appointed were not a peace offering, but a burnt offering and sin offering, in order to impress the mind of the parent with recollections of the origin of sin, and that the child inherited a fallen and sinful nature. The offerings were to be presented the day after the period of her separation had ended—that is, forty-first for a boy, eighty-first for a girl.

     8. bring two turtles, &c.—(See on Le 5:6). This was the offering made by Mary, the mother of Jesus, and it affords an incontestable proof of the poor and humble condition of the family (Lu 2:22-24).
