'Denarius' in the Bible

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

When those hired about the eleventh hour came, each one received a denarius.

When those hired first came, they thought that they would receive more; but each of them also received a denarius.

But he answered and said to one of them, ‘Friend, I am doing you no wrong; did you not agree with me for a denarius?

Show Me the coin used for the poll-tax.” And they brought Him a denarius.
