Luke 2:24 notes that Mary and Joseph offered 'a pair of turtledoves or two young pigeons (νοσσούς)' at Jesus' presentation in the temple, fulfilling the purification requirement of Leviticus 12:8 for those who could not afford a lamb. The term denotes newly hatched or very young birds still dependent on parental care. Classical Greek extends the metaphor to human infants and even to the young of other animals. The offering Mary brings signals her poverty yet also her obedience to the law. Simeon and Anna's subsequent recognition of the child Jesus adds dramatic irony: the parents bring the humble sacrifice of the poor, unaware they present the Lamb of God who will take away the sin of the world.
