The answer is: 20

Gen 37:28

When we dig into Genesis 37:28, we learn that Joseph was sold to the Ishmaelites for 20 shekels of silver—a striking figure that resonates throughout the tapestry of biblical stories. The context behind this sale is steeped in family betrayal; Joseph’s brothers grew envious of their father's favoritism, a classic tale of sibling rivalry. This moment marks a pivotal turn in Joseph's life, setting the scene for his dramatic rise from slavery to power in Egypt.

Ah, shekels! They were more than just currency back then; they signified worth, trade, and value. So 20 shekels was a low-stakes gambit regarding his life, much like a poker game gone wrong. Interestingly enough, tries to put that figure into perspective with common things from that era, such as a horse might go for about 100 shekels. So here’s Joseph, worth about a fifth of a horse—talk about low budget!

Throughout the Scriptures, the number 20 echoes on occasions in significant ways. It often symbolizes a moment of testing or unity, much like the trials Joseph will face and the eventual unity he will bring among the fractured family. What's also fascinating is how this act of betrayal ultimately sets the groundwork for the story of redemption for Joseph and his family, revealing themes of resilience and prophecy throughout the Bible. So, 20 shekels might just signify a lot more than a mere transaction!
