'Faithful' in the Bible

And the Lord said, Who then is that faithful and wise steward, whom his lord shall make ruler over his household, to give them their portion of meat in due season?

He that is faithful in that which is least is faithful also in much: and he that is unjust in the least is unjust also in much.

If therefore ye have not been faithful in the unrighteous mammon, who will commit to your trust the true riches?

And if ye have not been faithful in that which is another man's, who shall give you that which is your own?

And he said unto him, Well, thou good servant: because thou hast been faithful in a very little, have thou authority over ten cities.
