In the Bible, a mina is a unit of weight used in ancient times for measuring precious metals like gold or silver. It was also used to measure other commodities. The mina varied in weight across different ancient cultures and regions. In the Old Testament, particularly in the book of Ezekiel, a mina is mentioned as a unit of weight.

The Hebrew mina, also called the "maneh," was equivalent to around 50 shekels. The exact weight varied historically and geographically but was generally estimated to be around 500 grams to 600 grams (approximately 1.1 to 1.3 pounds) in various ancient contexts.

The New Testament also refers to the mina in the Parable of the Ten Minas (Luke 19:11-27), where a nobleman gave ten of his servants equal amounts of money to invest while he was away. Upon his return, he assessed their stewardship based on how they multiplied the entrusted minas.

Different ancient cultures had their variations of weight units, but the mina generally represented a substantial amount, often used in trade and commerce in biblical times.
