Parshat Bo - Redemption, Faith and Obedience

One important concept in Parshat Bo is the idea of redemption - specifically the redemption of Bnei Yisrael from slavery in Egypt and eventual entry into the land of Israel.

The Ramban comments on the theme of redemption in his commentary on Shmot 12:29-30, where the final plague of the death of the firstborn is described. Ramban explains that this plague was a punishment for Pharaoh and the Egyptians for their treatment of Bnei Yisrael and it was a demonstration of God's power and control. He also notes that it was also a way for Bnei Yisrael to be redeemed from slavery and to begin their journey towards freedom.

Another important concept in Parshat Bo is the idea of faith and obedience. Bnei Yisrael were commanded to mark their doorposts (mezuzot) with the blood of a lamb in order for the angel of death to pass over their homes during the final plague. This act required Bnei Yisrael to have faith in God's promise and to obey his commandments.

Rashi, in his commentary on Shmot 12:22, explains that this act was a way for Bnei Yisrael to show their faith in God and their obedience to his commandments. He notes that it was also a way for God to distinguish between Bnei Yisrael and the Egyptians and to protect Bnei Yisrael from the final plague.

Ramban, in his commentary on the same verse, explains that this act was a symbol of Bnei Yisrael' redemption and their separation from Egypt. He notes that by marking their doorposts with the blood of a lamb, Bnei Yisrael were identifying themselves as God's chosen people and as separate from the Egyptians.
