'Faithful' in the Bible

Now I, Nebuchadnezzar, praise and exalt and honor the King of heaven, for all His works are true and faithful and His ways are just, and He is able to humiliate and humble those who walk in [self-centered, self-righteous] pride.”

Then the [other two] commissioners and the satraps began trying to find a reason to bring a complaint against Daniel concerning the [administration of the] kingdom; but they could find no reason for an accusation or evidence of corruption, because he was faithful [a man of high moral character and personal integrity], and no negligence or corruption [of any kind] was found in him.
