The prophet describes the relationship between God and Am Yisrael in terms of a servant and master. Sacrifices are therefore necessary to enable the servant to stand before his master. The reason behind the redemption in the haftara is God's responsibility toward the nation as a master, who is obligated to care for his servants. The haftara ends with the prophet mocking idolaters who create their statues, and emphasizes God's role as a creator.
