The shekel in Biblical Hebrew is a unit of weight and currency that is smaller than both the talent and the mina. It was commonly used for trade and transactions and had different values depending on the historical era and location. In some contexts, it was equivalent to 20 gerahs.
In the New Testament and other Greek texts from antiquity, the talent was also a unit of weight and currency.
The Greek talent was typically lighter than the Hebrew talent, with a common weight of about 57 pounds (26 kilograms) or less.
In the parable of the talents in the New Testament (Matthew 25:14-30), talents were used as a representation of value and investment.
