'Teachers' in the Bible

Then sent I for Eliezer, for Ariel, for Shemaiah, and for Elnathan, and for Jarib, and for Elnathan, and for Nathan, and for Zechariah, and for Meshullam, chief men; also for Joiarib, and for Elnathan, who were teachers.

I have more understanding than all my teachers, for your testimonies are my meditation.

neither have I obeyed the voice of my teachers, nor turned my ear to those who instructed me!

Though the Lord may give you the bread of adversity and the water of affliction, yet your teachers won't be hidden anymore, but your eyes will see your teachers;

Your first father sinned, and your teachers have transgressed against me.
