In this passage, God is addressing Pharaoh through Moses, demanding the release of the Israelites from slavery in Egypt. God refers to Israel as His 'son,' indicating a special relationship and a sense of ownership and care. The request for freedom is not just for liberation but specifically so that the Israelites can worship God, highlighting the centrality of worship in their identity and purpose.
Pharaoh's refusal to let the Israelites go is met with a grave warning: the death of his firstborn son. This foreshadows the final and most devastating of the ten plagues that God would bring upon Egypt. The passage illustrates the seriousness of opposing God's will and the lengths to which God will go to ensure His people can fulfill their calling. It also reflects the theme of justice and divine retribution, as Pharaoh's hardened heart leads to dire consequences. This narrative encourages believers to recognize the importance of obedience to God and the value He places on the freedom to worship.
