For anyone who is interested here the ancient text which i mentioned :
"Come to me, Thoth, O noble Ibis. O god who longs for Khmunu, O dispatch-writer of
the Ennead, the great one of Unu. Come to me that you may give advice and make
me skillful in your office.
Better is your profession than all professions. It makes men great. He who is skilled
in it is found fit to exercise the office of magistrate. I have seen many for whom you
have acted and they are in the council of the Thirty, they being strong and powerful
through what you have done.
You are the one who has given advice. You are the one
who has given advice to the motherless man. Shay and Renenwetet are with you.
Come to me that you may advise me.
I am the servant of your house. Let me relate your prowess in whatever land I am.
Then the multitude of men shall say "How great are the things that Thoth has done."
Then they shall come with their children to brand them with your profession, a
calling good to the Lord of Victory. Joyful is the one who has exercised it. (Lewis, 255)
