Exodus 34:19
All that openeth the matrixe is mine: and euery firstling amongst thy cattell, whether oxe or sheepe, that is male. Exodus 34:19 (KJV)
Historical Context: In Exodus the Israelites have been led out of slavery in Egypt by the hand of God through Moses. At this point in the narrative Moses has ascended Mount Sinai to receive the Ten Commandments and other laws from God. The first tablets were broken because of the golden calf, and now God is renewing the covenant with the people.
The phrase “openeth the matrix” refers to the firstborn, the first male child born in a family or the firstborn of cattle. God is asserting His ownership and claim over every firstborn. The firstborn held special significance in ancient cultures, including Israel, and the verse reminds the people that the firstborn belongs to God, signifying His sovereignty and authority over all creation. The command also extends to the firstborn of livestock, specifically mentioning oxen and sheep. The firstborn male animal was to be consecrated to God as an offering.
Symbolic and Spiritual Significance: This verse had practical implications for the Israelites in terms of their offerings and dedications, but it also carried deep symbolic meaning. The firstborn was a reminder of God’s deliverance of Israel from Egypt when He spared the firstborn of Israel during the final plague (Exodus 12:13). By offering the firstborn, the people remembered God’s faithfulness and were called to obedience.
Application for Christians today: Although offering firstborn animals is not applicable to New Testament believers, the principle of dedicating the first and best of what we have to God remains relevant. Christians are encouraged to give God the firstfruits of their material possessions, time, talents, and resources. Proverbs 3:9‑10 (KJV) exhorts, “Honour the Lord with thy substance, and with the firstfruits of all thine increase: So shall thy barns be filled with plenty, and thy presses shall burst out with new wine.” In the New Testament, Christ is called the “firstborn” over all creation (Colossians 1:15), and believers are urged to present themselves as living sacrifices, holy and acceptable to God (Romans 12:1). This spiritual offering involves dedicating our entire lives to God and following His will.
In conclusion, Exodus 34:19 teaches us to give the first and best of what we have to God, acknowledging His sovereignty and remembering His faithfulness. As Christians we are called to offer ourselves as living sacrifices, putting God first in every aspect of our lives.
