Isaiah 30:20-21

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: {affliction: or, oppression} And thine ears shall hear a word behind thee, saying, This {is} the way, walk ye in it, when ye turn to the right hand, and when ye turn to the left.
