an Hebrew day dont have hours , the day starts in the evening after
you can see the first three stars in the sky ,so every day can have
a diferent amount of hours ,I`m not sure ,but I think the Greeks
were the first to divide the day in hours .
and yes, the bible defenetly sayes day ("Yom"),and even explaine
the day starts in the evening ,and ends in the morning ,and that
he call the lighted time "Yom" (day) .
a time that includs the Lighted time and the darked time togueder
(or todays 24 hours) is called "Yimama " ,but this word didnt existed
then yet ,so the word "yom" (day) ,is used for both ,the lighted time ,
and the piriod between the evening till the morning next .
Every thing I write, wrote, or will write, its in my own opinion, for I have no other.
Release me from the duty of being polite and remind you, "I made use of my own brain".
