I dont ever remember reading of elders school in the Bible, oh that is right the Bibles says
Hebrews 8:10-13
10 “‘For this is the covenant that I shall covenant with the house of Israel after those days,’ says Jehovah. ‘I will put my laws in their mind, and in their hearts I shall write them. And I will become their God, and they themselves will become my people.
11 “‘And they will by no means teach each one his fellow citizen and each one his brother, saying: “Know Jehovah!” For they will all know me, from [the] least one to [the] greatest one of them. 12 For I shall be merciful to their unrighteous deeds, and I shall by no means call their sins to mind anymore.’”
13 In his saying “a new [covenant]” he has made the former one obsolete. Now that which is made obsolete and growing old is near to vanishing away.
