Biblical numerology involves the study of numbers within the scriptures, seeking to understand their symbolic significance. While certain numbers like 3, 7, and 40 are widely recognized for their positive connotations, the interpretation of thirteen often leans towards the negative, particularly within certain Christian traditions. This stems primarily from its association with events considered inauspicious.
The perceived negativity surrounding this integer is not explicitly stated within the Bible itself as an inherent property. However, the Last Supper, a pivotal event leading to the crucifixion of Jesus, involved thirteen individuals Jesus and his twelve disciples, including Judas Iscariot, who betrayed him. This association, though not a direct biblical statement about the integer itself, contributed significantly to its unfavorable reputation in some theological interpretations. The number is also linked to rebellion, primarily with the thirteen rebellious kings mentioned in Genesis 14.
