'Teachers' in the Bible

So I sent for Eliezer, Ariel, Shemaiah, Elnathan, Jarib, Elnathan, Nathan, Zechariah and Meshullam, leading men, and for Joiarib and Elnathan, teachers.

I have more insight than all my teachers,For Your testimonies are my meditation.

“I have not listened to the voice of my teachers,Nor inclined my ear to my instructors!
