'Minas' in the Bible

And he summoned ten of his slaves, gave them ten minas, and said to them, 'Do business with these until I come back.'

So the first one came before him and said, 'Sir, your mina has made ten minas more.'

Then the second one came and said, 'Sir, your mina has made five minas.'

But they said to him, 'Sir, he has ten minas already!'
