John Lightfoot on Luke 16:11

[If ye have not been faithful in the unrighteous mammon, &c.] The Vulgar, If ye have not been faithful in the unjust mammon: it is not ill rendered. But can any one be faithful in the unrighteous mammon? As to that, let us judge from the example of Zaccaeus: although he was not faithful in scraping together any thing unjustly, yet was he eminently faithful in so piously distributing it.
