Who is a woman?
A woman is an adult female human.
What is a virtue?
A virtue is a particular manifestation of moral excellence in a person; an admirable quality.
What is lost?
Lost which is the past participle of lose means ruined or destroyed, either physically or morally; past help or hope.
To sum it up, when it is said, woman thou has lost thou value, it simply means that an adult female human has ruined or destroyed a moral excellence or an admirable quality that has been manifested in most adult female human of the past.
Morals here means conforming to a standard of right behaviour; sanctioned by or operative on one's conscience or ethical judgement. Morals in this context refers to good morals.
The truth of the matter is that the word "moral, good and basis relative, your definition of moral, good and bad, may be totally different from mine.
During the days of our mothers, good morals was held in high esteem; a lot of today's normalities were abnormal those days and seriously frowned at, the rate of discipline and respect was at the high side.

WHAT HAS HAPPENED ?

95% of women including those under 18 and above 30, have lost so many moral virtues, (base on my observation).
The rate at which girls dress naked in the name of getting a man for reasons best known to them is appalling. Little did they know, that the same men don't see value in them. Don't dress to kill, dress to attract the kind of man that will value, cherish and respect you.
Its a pity how women compare themselves to men, drinking and smoking, damaging their delicate internal organs; how having multiple sex partners is the order of the day; men can no longer vouge for their woman.

It brings tears in my eyeshow abortion has become a norm in this generation.
Where has thou kept thou conscience?, killing what you can't create, that tender soul that has done no harm; God has thought of a problem to solve; and has just sent that problem silver through you, and all you could do was to oil it, taking away what you can't give; think about it, what if you were killed? Maybe you wouldn't make the world an evil place.

WOMAN WHAT VALUE DO YOU HAVE LEFT?

dressed in the finest of clothes, wearing the most expensive hair, with the best makeup, and yet an evil heart.

Where is that kind heart that gathers crowd to you?!!!, that brings you favour?!!! That opens doors for you?!!!.
Where is that humility that attracts the praise of men to you?!!!
Where is that gentle words that makes your voice loud?!!!
Where is that generous hands that brings plenty?!!
Where is that hand that brings grains?!!!
WHERE?!!! WHERE?!!! WHERE?!!!
WOMAN THOU HAS LOST THOU VIRTUE!!!.
