'Truthful' in the Bible
Should [God's] recompense [for your sins] be as you will it, when you refuse to accept it? For you must do the choosing, and not I; therefore say what is your truthful conclusion.
For there is nothing trustworthy or steadfast or truthful in their talk; their heart is destruction [or a destructive chasm, a yawning gulf]; their throat is an open sepulcher; they flatter and make smooth with their tongue.
Truthful lips shall be established forever, but a lying tongue is [credited] but for a moment.
A truthful witness saves lives, but a deceitful witness speaks lies [and endangers lives].
As it is written, None is righteous, just and truthful and upright and conscientious, no, not one.
Amid honor and dishonor; in defaming and evil report and in praise and good report. [We are branded] as deceivers (impostors), and [yet vindicated as] truthful and honest.
[Resting] in the hope of eternal life, [life] which the ever truthful God Who cannot deceive promised before the world or the ages of time began.
