¹⁹ “All the firstborn males that are born of your herd and flock you shall dedicate to the Lord your God. You shall do no work with the firstborn of your herd, nor shear the firstborn of your flock. ²⁰ You shall eat it, you and your household, before the Lord your God year by year at the place that the Lord will choose. ²¹ But if it has any blemish, if it is lame or blind or has any serious blemish whatever, you shall not sacrifice it to the Lord your God. ²² You shall eat it within your towns. The unclean and the clean alike may eat it, as though it were a gazelle or a deer. ²³ Only you shall not eat its blood; you shall pour it out on the ground like water.” – Deuteronomy 15:19-23 ESV

Moses returns to a subject that he had brought up earlier: The offering of the firstborn.

“There you will bring your burnt offerings, your sacrifices, your tithes, your sacred offerings, your offerings to fulfill a vow, your voluntary offerings, and your offerings of the firstborn animals of your herds and flocks.” – Deuteronomy 12:6 NLT

“But you may not eat your offerings in your hometown—neither the tithe of your grain and new wine and olive oil, nor the firstborn of your flocks and herds, nor any offering to fulfill a vow, nor your voluntary offerings, nor your sacred offerings.” – Deuteronomy 12:17 NLT

“Bring this tithe to the designated place of worship—the place the Lord your God chooses for his name to be honored—and eat it there in his presence. This applies to your tithes of grain, new wine, olive oil, and the firstborn males of your flocks and herds. Doing this will teach you always to fear the Lord your God.” – Deuteronomy 14:23 NLT

But what is the offering of the firstborn and why was it so important? To understand its significance we have to look back to the book of Exodus and the final plague that God brought upon the people of Egypt.

And that night at midnight, the Lord struck down all the firstborn sons in the land of Egypt, from the firstborn son of Pharaoh, who sat on his throne, to the firstborn son of the prisoner in the dungeon. Even the firstborn of their livestock were killed. Pharaoh and all his officials and all the people of Egypt woke up during the night, and loud wailing was heard throughout the land of Egypt. There was not a single house where someone had not died. – Exodus 12:29-30 NLT

This devastating event took place in conjunction with the establishment of the Passover. God had warned the people of Israel that He was bringing judgment upon the land of Egypt and He had mercifully provided the people of Israel with a means of avoiding His wrath. When His judgment came, it would be non-discriminatory, bringing death to the firstborn of every family living in the land of Egypt, whether Egyptian or Jew. Even the animals belonging to the Egyptians and Jews would suffer under God’s judgment…unless.

The truth was that all deserved God’s judgment. Even the Israelites had long ago abandoned their worship of Yahweh for the false gods of Egypt, and they stood fully condemned before God. But He provided them with a means of escaping His judgment – if they would trust His word and obey His command.

“Announce to the whole community of Israel that on the tenth day of this month each family must choose a lamb or a young goat for a sacrifice, one animal for each household. If a family is too small to eat a whole animal, let them share with another family in the neighborhood. Divide the animal according to the size of each family and how much they can eat. The animal you select must be a one-year-old male, either a sheep or a goat, with no defects.

 “Take special care of this chosen animal until the evening of the fourteenth day of this first month. Then the whole assembly of the community of Israel must slaughter their lamb or young goat at twilight. They are to take some of the blood and smear it on the sides and top of the doorframes of the houses where they eat the animal. That same night they must roast the meat over a fire and eat it along with bitter salad greens and bread made without yeast. Do not eat any of the meat raw or boiled in water. The whole animal—including the head, legs, and internal organs—must be roasted over a fire. Do not leave any of it until the next morning. Burn whatever is not eaten before morning.” – Exodus 12:3-10 NLT

As long as the Israelites did exactly as God had commanded them to do, the firstborn of their families and flocks would be spared. The blood of the lamb, sprinkled on the doorframes of their homes, would cause the Death Angel to “pass over” them. They would be spared the judgment of God.

And the Israelites, having followed God’s instructions, were preserved by God, while the Egyptians suffered tremendous loss of life. And devastated by the loss of his own son, Pharaoh finally relented and allowed the Israelites to leave. And God commanded the people of Israel:

“Dedicate to me every firstborn among the Israelites. The first offspring to be born, of both humans and animals, belongs to me.”  – Exodus 13:2 NLT

God had spared from death the firstborn among the Israelites and, therefore, considered them as belonging to Him. But later on, God would set apart the tribe of Levi as the surrogates or stand-ins for the rest of the firstborn of Israel.

“Look, I have chosen the Levites from among the Israelites to serve as substitutes for all the firstborn sons of the people of Israel. The Levites belong to me, for all the firstborn males are mine. On the day I struck down all the firstborn sons of the Egyptians, I set apart for myself all the firstborn in Israel, both of people and of animals. They are mine; I am the Lord.” – Numbers 3:12-13 NLT

The tribe of Levi would serve in the place of all the firstborn of Israel, and from within the Levites would come the priests who served in God’s tabernacle. They would dedicate their lives to the service of the people of God.

But the firstborn of the animals would always belong to God and He required that the people of Israel dedicate them to Him through sacrifice. It was to be an act of obedience and gratitude to God for His having spared them during that fateful night when the Death Angel passed over all the homes in Egypt. As long as the firstborn lamb or bull was alive, they were to be preserved for God. The Israelites were not allowed to shear their wool for clothing. They could not use a firstborn bull to pull a plow. These animals were to be seen as the permanent possessions of God.

And all of this foreshadows another firstborn who would also be dedicated to God and destined for sacrifice. Jesus Christ is described by the apostle Paul as “the image of the invisible God, the firstborn of all creation” (Colossians 1:15 ESV).

Elsewhere Paul writes that “Jesus gave his life for our sins, just as God our Father planned, in order to rescue us from this evil world in which we live” (Galatians 1:4 NLT). Jesus was the sinless lamb of God, who offered His life as a substitute for sinful mankind. He stood in our place. He took the punishment we deserved. And when we place our faith in Him, the wrath of God passes over us. His blood, sprinkled on the doorframes of our hearts, serves as a payment for our sin debt, satisfying the just and righteous wrath of God and allowing us to enjoy new life, rather than death.

And as a result of our faith in Christ, we become the firstborn, dedicated to God for His service. Paul makes this point perfectly clear in his letter to the Romans.

For God knew his people in advance, and he chose them to become like his Son, so that his Son would be the firstborn among many brothers and sisters. – Romans 8:29 NLT

We belong to Him. We are His holy possession and our lives are to be dedicated to His use.

Don’t you realize that your body is the temple of the Holy Spirit, who lives in you and was given to you by God? You do not belong to yourself, for God bought you with a high price. So you must honor God with your body. – 1 Corinthians 6:19-20 NLT

The Levites became the firstborn of God, serving in the place of all the other Israelites whom God had deemed as His own. They sacrificed their lives in service to God on behalf of all the people of God. And the firstborn bulls, sheep, and goats were dedicated to God, reserved for His use and destined to give their lives in worship of Him.

But today, those of us who are in Christ, enjoy a relationship with God due to the substitutionary death of the firstborn, the sinless Lamb of God. And now, we find ourselves living as the Levites did, set apart by God for His glory. And Peter would have us remember that we are “a chosen race, a royal priesthood, a holy nation, a people for his own possession” (1 Peter 2:9 ESV). We belong to Him. Our lives are to be set apart unto Him. We are not our own, but we belong to God, having been bought by Him at a very high price: The death of His own sinless Son.
