What Does 13 Mean In The Bible

Background Information

The number 13 has many special connotations; some believe it is a lucky number while others foresee bad fortune or impending doom with the number. In the Bible, the number thirteen is significant with many interpretations and implications. Whether the number has positive or negative symbols throughout the Bible or both, the number thirteen itself holds a significant importance in the Bible.

History of the Number 13

13 is seen as a divine number since long ago, since before Christianity and even Judaism. Number 13 was seen as a special number due to its numerous significances. In Ancient Egypt it was synonymous to total completeness and eternal life. They also viewed it as a trinity of 3 gods (Earth, Sunrise and Nile). In Ancient China 13 was used as a symbol of fortunate occasions, resolving a bad situation, new beginnings and even for love. Furthermore, the significance of the number was used by the Greeks and the Judaic priests in whose ancient Talmud 13 is also recognized as a number related to prophecy and faith.

Meaning in the Bible

The number thirteen is often associated with the number 12 in the Bible, and is usually seen as something that goes beyond the normal, such as in 12 apostles plus Jesus (13 symbolic entities of the Kingdom of God). Apart from the number twelve, we tend to forget the importance of the number thirteen in the Bible. The Bible refers to thirteen deities (the 12 tribes of Israel plus God), thirteen friends of Job, which is a sign of loyalty, and the twelve tribes of Israel, which are represented by twelve stones and an extra stone to refer to God.
Another symbolic reference to the number thirteen in the Bible is the story of Jesus’ Last Supper, and it being attended by thirteen people. Furthermore, it is commonly assumed that Jesus was crucified on the thirteenth day of the Jewish month of Nisan. The symbolism of 13 people in attendance at the meal along with Jesus is meant to represent the coming together of different nations and faiths, to represent the unity of mankind under one God and the faith He asks us to choose.

Connections to Christianity

The number thirteen has very strong connections to Christianity. Christianity is based in part on the events of the Bible and thirteen has a big symbolic importance. An example would be the Last Supper, which was attended by thirteen people, as it symbolizes the unity of mankind under God.
Furthermore, the number thirteen is associated with the Holy Trinity of God, Jesus, and the Holy Spirit, which are symbolically seen as a single entity in the same way that the number thirteen is seen as a unified number even though it is composed of many different elements.
Finally, 13 generations were counted from the start of Solomon until the Babylonian exile, and the genealogy of Jesus was counted as a result of thirteen generations from his father Joseph to Noah.

Connection to Satan

Apart from Christianity, the number thirteen may also be associated with Satan or bad luck. Number thirteen was once referred to as “the witch’s number” since it had long been believed by many to be a sign of bad luck or a connection to the devil.
For instance, in the Bible Thirteen is the number that Satan chose to tempt Judas Iscariot. This was a deliberate action since it was always remembered as an unlucky number before then. Furthermore, it is said that Judas broke the bread of the Last Supper before the blessed food was distributed, which again suggests its link to bad luck.

Meaning for Modern Times

What does 13 mean in the Bible for modern times? With the association of the number thirteen to Satan and bad luck, many avoid using the number, which also means that it’s less prevalent in today’s culture.
In contrast, some believe the number to be a sign of good luck, citing examples from the Bible like Jesus and the twelve apostles, which could be interpreted as a lucky 13 rather than bad luck.
Either way, 13 carries with it symbolism that transcends time and culture, and can still be seen as a symbol of good and bad today.

Expert Perspectives

According to Professor John Miller at Harvard Divinity School, “the number thirteen carries with it a great amount of symbolism in the Bible. In the Old Testament, we find thirteen mentions of the number thirteen in connection to the Israelites, implying significance from God. In the New Testament, the number thirteen is associated with the apostles attending the Last Supper, and the 13 generations from Noah to Jesus.”
He further adds, “it is also a number that is associated with bad luck in modern culture, suggesting that the association goes beyond time and culture.”


The number thirteen carries with it significant symbolism in both Christianity and in the Bible. It is a number that is associated with holiness and the unity of mankind, as well as with the devil and bad luck. Its symbolism has transcended time and culture, making it a powerful representation of both positive and negative connotations.
Through the stories associated with it in the Bible, it has been immortalized as a number with great significance to both Christians and non-Christians alike. Its symbolism has been important throughout history, and its various connotations give it a power that remains even today.

Connection to Natural Cycles

The number 13 relates to natural cycles, from the cycles of the moon to the cycle of one’s life. It is associated with the idea of moving forward, completing a cycle and starting anew. This is evident in its relationship to the new moon, which marks the start of a new cycle.
13 also has a relationship to the human life cycle, from conception to birth. The gestation period is around nine months, therefore 13 weeks are needed for a new life to be born. This is a perfect cycle and one could say it is complete when the thirteenth week passes.

Modern Practices

In modern times, 13 is still seen as a symbol of luck, whether good or bad. There are many superstitions and traditions associated with the number that are still practiced today.
For instance, Friday the 13th is often seen as a day of bad luck in modern culture, and some people avoid doing things on this day or believe that strange events will occur on this day. There are also some people who believe that if they pass the number 13 on a house or vehicle, they will be lucky, and some people even avoid dwelling on the 13th floor of a building.

Meaning for Today

The importance of the number 13 and its symbolism is still prominent today. It is a number that holds immense significance for many people and its connotations still stand strong in our society.
Whether it be seen as a symbol of luck, unity, or bad luck, 13 still carries a powerful meaning and important symbolism. As we can see from its connections to Christianity, Satan, and nature, it is a number that will forever be part of history, and the lessons and stories that come with it, remain important today.
