Honesty

First of all what does it mean to be honest.
It is more than not telling a lie it is about
speaking truth under all circumstances.
Other words you could be in front of a
firing squad and you still speak the truth.
You have a strong belief in what you are saying.

The word honest is used as an adjective and

as an adverb. As an adjective the person is

sincere without deceit and untruthfulness.

Example: "I haven't totally been honest with you."

As an adverb used to persuade someone of the truth of something

Example:  "you'll like it when you get there, honest".

Both the adjective and adverb definitions and examples

come from the Oxford languages.

Honest is defined by Merriam-Webster Dictionary as

good and truthful: not lying, stealing, or cheating : 

showing or suggesting good and truthful character :

not hiding the truth about someone or something:

not meant to deceive anyone. 

The word honest in Greek in the New Testament

by Strong's Concordance is  kal-os'; of uncertain 

affinity; properly beautiful, but chiefly (figurative) 

good (literal or moral), i.e. valuable or virtuous 

(for appearance or use, and thus distinguished from

 (18) (ἀγαθός), which is properly intrinsic): — x better,

 fair, good (-ly), honest, meet, well, worthy.

 In the New Testament being an honest person you

are good, beautiful, valuable, distinguished from 

to others and worthy. 

In the Old Testament Isaiah had a warning in chapter

5 verses 20 and 21 Woe to those who call evil good 

and good evil, who put darkness for light

and light for darkness, who put bitter for sweet and sweet

for bitter. Woe to those that are wise in their own eyes,

and clever in their own eyes.

Today often those who are honest are called dishonest

and those call dishonest as though they are honest.
