Matthew 20:4
And to them he said: you go into the vineyard too, and whatever is right I will give you. So they went. The promise of whatever is right — without specifying an amount — is the basis on which the third-hour workers go into the vineyard. The open-ended promise creates the ambiguity that the day's end will resolve: what is right according to the kingdom's economy may differ from what is right according to the labor market's economy.
