Jesus, the Lord of the law and the maker of the rules of our universe, went voluntarily with his mother to obey the Mosaic Law, i.e. the law of circumcision and expiation, as it was prescribed in the book of Leviticus  12:6-8.
Saint Luke [2:22-23] tells us that “when the day came for them to be purified in keeping with the Law of Moses, they took him up to Jerusalem to present him to the Lord”. Today, the Most Holy One, stands with his mother the purest of all, in the shoes of sinners, they offer the offering of poor people, in order to give a lesson in lowering ourselves under the jaw of his divine law, where we are at safety from pride.
Saint Luke [2:26-39] links well this event of the presentation of Our Lord to the Temple of His Father, to the rest of the Economy of Salvation, he explains that

The child's father and mother were amazed at what was said about him; and Simeon blessed them and said to Mary his mother, ‘Behold, this child is destined for the fall and rise of many in Israel, and to be a sign that will be contradicted (and you yourself a sword will pierce) so that the thoughts of many hearts may be revealed.”

[Lev 12:7] The priest shall offer them up before the LORD to make atonement for her, and thus she will be clean again after her flow of blood. Such is the law for the woman who gives birth to a boy or a girl child.
[Lev 12:8] If, however, she cannot afford a lamb, she may take two turtledoves or two pigeons, the one for a holocaust and the other for a sin offering. The priest shall make atonement for her, and thus she will again be clean."
 Personally, I don’t understand wherefrom the author of the Maronite Sinksar came up with this payment of 5 silver denarius. Neither Lev. 12:6-8, nor Luke 2:24 mentioned anything about money offering! Probably that was a later Jewish tradition, requiring an extra money offering, for the priest performing the circumcision.
