The Numbers
The number of animal sacrifices performed in the Bible is truly staggering. In “Animal Welfare: A Quantitative Study of Fundamentalist Biblical Dishonesty,” Brian Bolton presents instances of animal sacrifice and animal cruelty as well as descriptions of animal sacrifices in the Bible. According to his “top-ten” list, biblical animal sacrifices number in the hundreds of thousands.

Famous Sacrifices
Noah’s Sacrifice to God
In Genesis 8:20-21, Noah “took of every clean animal and of every clean bird and offered burnt offerings on the altar.” When the Lord “smelled the pleasing odor,” he promised to never again destroy all living things on earth.
The Command to Sacrifice Isaac
In Genesis 22:1-14, one of the most famous Bible stories, God tests Abraham by commanding him to kill his beloved son, Isaac. Just as Abraham goes to kill Isaac, an angel intercedes, telling Abraham not to kill his son because he has proven his obedience to God. Abraham sees a ram caught in a thicket by its horns — which some translations understand to have been provided by God — and sacrifices it instead of Isaac.
The First Passover
Exodus 12 narrates the establishment of Passover in anticipation of the plague that finally persuades Pharaoh to free the Israelites. God commands Moses and Aaron to instruct each Israelite family to slaughter an unblemished lamb, smear its blood on their doorframes, and eat the lamb. God passes over the households marked by the lamb’s blood and kills every firstborn in Egypt without the mark, including the firstborn livestock. He later gives Moses and Aaron directions for future Passover celebrations and details the necessary animal sacrifice.

Jesus: Son of God, Redeemer, and Animal-Rights Activist?
In John 2:13-16, Jesus famously cleanses the temple in Jerusalem by driving out the people selling cattle, sheep, and doves. Some animal-rights activists claim that Jesus’ opposition to animal sacrifice—the Temple’s primary revenue stream—was the triggering event that angered the Temple Priests and ultimately led to the Crucifixion.
