'Teachers' in the Bible

Go, gather the elders (tribal leaders) of Israel together, and say to them, ‘The Lord, the God of your fathers, the God of Abraham, of Isaac, and of Jacob, appeared to me, saying, “I am indeed concerned about you and what has been done to you in Egypt.

So I sent for Eliezer, Ariel, Shemaiah, Elnathan, Jarib, Elnathan, Nathan, Zechariah, and Meshullam, [who were] leading men, and also for Joiarib and Elnathan, [who were] teachers.

I have better understanding and deeper insight than all my teachers [because of Your word],For Your testimonies are my meditation.

“I have not listened to the voice of my teachers,Nor have I inclined my ear to those who instructed me.

“Your first father [Jacob] sinned,And your spokesmen [the priests and the prophets—your mediators] have transgressed against Me.

And the people to whom they are prophesying will be thrown out into the streets of Jerusalem, victims of famine and sword; and they will have no one to bury them—neither them, nor their wives, nor their sons, nor their daughters. For I will pour out their [own] wickedness on them [and not only on the imposters posing as prophets, for the people could not have been deceived without their own consent].

Those who are [spiritually] wise will shine brightly like the brightness of the expanse of heaven, and those who lead many to righteousness, [will shine] like the stars forever and ever.

Many will be purged, purified (made white) and refined, but the wicked will behave wickedly. None of the wicked shall understand, but those who are [spiritually] wise will understand.
