Also called Prices in the Bible, Wages and prices.
Every price the text names on one ladder of days' pay, from the widow's two small coins to the servant's ten-thousand-talent debt.
Scripture prices things constantly, and the denarius makes the prices readable: a day's wage by the parable's own terms, so every sum in the gospels is a length of time. Laid on one ladder they run across ten orders of magnitude, which is why it steps by tens rather than by days. The bottom rung is the widow's gift, a sixty-fourth of a day and all she had. The top is the debt the king forgave in Matthew 18, and the same parable sets the fellow servant's hundred denarii beside it: the gap between them is the sermon. Two things are reckoned rather than read. Old Testament prices are in shekels of silver, and are placed at first-century pay, a shekel being worth a stater (the coin that paid the temple tax for two), so Joseph's twenty shekels sit centuries away from the wages they are measured in. And a talent has two honest values in days, the Greek six thousand drachmas and the Hebrew three thousand shekels, so the talents are drawn as a range rather than a point.
A day’s pay is a denarius by the text’s own terms, so every coin in the gospels reads as time. The widow’s two coins sit at the bottom of the ladder and the king’s debt at the top, and the servant forgiven that debt then took a man by the throat over a hundred denarii.
Not a word scripture uses. A reading aid, not a word the text uses. It gathers the prices scripture states and sets them in the one unit the text itself defines, the denarius as a day's wage.
