How do we know that the number twelve is significant in the Bible?

In biblical numerology, the number twelve signifies completeness and perfection, as seen through its connections to the twelve tribes of Israel and the twelve apostles of Christ. Mark 8 discusses the twelve baskets of leftover bread after the feeding of the five thousand, illustrating God's provision and the sufficiency of Christ as the Bread of Life. The twelve tribes received God's law, and the apostles preached the Gospel, showing that God’s perfect plan for salvation is rooted in His complete work through Christ, who fulfills the law perfectly.
