According to Luke 2:21–24, Joseph and Mary brought two birds at the required time. This reflects the humble circumstances in which Jesus was born. The Saviour of the world is born in a stable. His earthly parents are poor; they cannot afford a lamb for the burnt offering. Yet, Mary has given birth to the Lamb who would be offered up to deliver his people from death and darkness.
8 Si elle n'a pas de quoi se procurer un agneau, elle prendra deux tourterelles ou deux jeunes pigeons, l'un pour l'holocauste, l'autre pour le sacrifice d'expiation. Le sacrificateur fera pour elle l'expiation, et elle sera pure.
