'Denarius' in the Bible

When he had agreed with the laborers for a denarius a day, he sent them into his vineyard.

"When those who were hired at about the eleventh hour came, they each received a denarius.

When the first came, they supposed that they would receive more; and they likewise each received a denarius.

"But he answered one of them, 'Friend, I am doing you no wrong. Didn't you agree with me for a denarius?

Show me the tax money." They brought to him a denarius.
