and to offer a sacrifice according to what is said in the law of the Lord, A pair of turtledoves, or two young pigeons.a Bible
From Lev. 12:8.

“A pair of turtledoves.” Quoted from Leviticus 12:8. This verse contains important information concerning the timing of the events of the birth of Jesus. According to Leviticus 12:8, a woman was only allowed to bring a pair of turtledoves or two young pigeons as a sacrifice after childbirth if she could not afford a lamb. Mary’s cleansing and the presentation of Jesus in the Temple would have been 40 days after the birth of Jesus (Lev. 12:2-4). Mary and Joseph would have made the 7 mile walk with Jesus from Bethlehem to the Temple in Jerusalem to present Jesus only because Bethlehem was so close to the Temple. Women were not expected to travel far after childbirth. After presenting Jesus and making the sacrifices, they went back to Bethlehem, where Joseph had no doubt found work. The Magi would arrive on the scene almost two years later. Had they already come and been with the shepherds at the manger, as tradition teaches, then the gold, frankincense, and myrrh, that they brought would have made Joseph and Mary far too wealthy for her sacrifice of the doves or pigeons to be accepted by God. The idea that Joseph and Mary would not have brought a lamb because Jesus was the lamb cannot be substantiated. They, of all people, would have kept the Levitical Law.
