“will be called holy to the Lord.” This command to set apart and redeem the firstborn male was from the Mosaic Law (Exod, 13:2, 12; Num. 18:15-16). Every male child was to be redeemed, and the redemption price was five shekels of silver, about 2 ounces (Num. 18:15-16). In the case of the birth of Jesus, when Joseph and Mary went to the Temple to offer the sacrifices required for Mary’s purification after childbirth—a lamb for a burnt offering and a bird for a sin offering (Lev. 12:6)—they also offered the 5 shekels of silver as the price of redemption (or “ransom”) of baby Jesus. In the case of Joseph and Mary, they were too poor for a lamb, so they offered birds (Luke 2:24; Lev. 12:8).
