Denarius (containing ten), Authorized Version “penny,” Matt. 18:28; 20:2, 9, 13, a Roman silver coin in the time of our Saviour and the apostles, worth about 15 cents. It took its name from its being first equal to ten “asses,” a number afterwards increased to sixteen. It was the principal silver coin of the Roman commonwealth. From the parable of the laborers in the vineyard it would seem that a denarius was then the ordinary pay for a day’s labor. Matt. 20:2, 4, 7, 9, 10, 13.
