'Faithful' in the Bible

And the Lord said, 'Who, then, is the faithful and prudent steward whom the lord shall set over his household, to give in season the wheat measure?

He who is faithful in the least, is also faithful in much; and he who in the least is unrighteous, is also unrighteous in much;

if, then, in the unrighteous mammon ye became not faithful -- the true who will entrust to you?

and if in the other's ye became not faithful -- your own, who shall give to you?

and he said to him, Well done, good servant, because in a very little thou didst become faithful, be having authority over ten cities.
