'Faithful' in the Bible

The Lord said, "Who, then, is the faithful and careful servant manager whom his master will put in charge of giving all his other servants their share of food at the right time?

Whoever is faithful with very little is also faithful with a lot, and whoever is dishonest with very little is also dishonest with a lot.

So if you haven't been faithful with unrighteous wealth, who will trust you with true wealth?

And if you haven't been faithful with what belongs to foreigners, who will give you what is your own?
