'Teachers' in the Bible

I have more understanding than all my teachers: for thy testimonies are my meditation.

And have not obeyed the voice of my teachers, nor inclined mine ear to them that instructed me!

And though the Lord give you the bread of adversity, and the water of affliction, yet shall not thy teachers be removed into a corner any more, but thine eyes shall see thy teachers:

Thy first father hath sinned, and thy teachers have transgressed against me.
