In Luke 2:21, it is mentioned that Jesus was circumcised on the eighth day, in accordance with Jewish custom and the law of Moses. This act symbolized Jesus' dedication to God and his submission to the Jewish religious practices of his time. The passage serves as a reminder of Jesus' humanity and his fulfillment of the Old Testament prophecies regarding the Messiah.

The act of circumcision was important in the Jewish faith as a sign of the covenant between God and the people of Israel. It is also a foreshadowing of Jesus' sacrifice on the cross for the redemption of humanity. This passage highlights the importance of following religious traditions and obeying God's commands while also emphasizing the significance of Jesus' role as the Savior of the world.

Luke 2:21 is unique to the Gospel of Luke and is not found in other parts of the gospels. Its mention of Jesus' circumcision provides a valuable insight into his early life and serves as a foundation for understanding his ministry and mission on earth. As a daily application, Christians can reflect on the obedience and faithfulness of Jesus in fulfilling God's plan and seek to emulate his example in their own lives.
