'Faithful' in the Bible

This is a faithful saying, and worthy of all acceptation, that Christ Jesus came into the world to save sinners; of whom I am chief.

Even so must their wives be grave, not slanderers, sober, faithful in all things.

This is a faithful saying and worthy of all acceptation.

And they that have believing masters, let them not despise them, because they are brethren; but rather do them service, because they are faithful and beloved, partakers of the benefit. These things teach and exhort.
