'Faithful' in the Bible

"Who, then," replied the Lord, "is the faithful and intelligent steward whom his Master will put in charge of His household to serve out their rations at the proper times?

If therefore you have not proved yourselves faithful in dealing with the wealth that is tainted with fraud, who will entrust to you the true good?

And if you have not been faithful in dealing with that which is not your own, who will give you that which is your own?

"'Well done, good servant,' he replied; 'because you have been faithful in a very small matter, be in authority over ten towns.'
