{In the past,} my Master (God) gave you sorrow and hurt--it was like the bread and water you ate every day. But God is your teacher, and he will not continue to hide from you. You will see your teacher with your own eyes.
Then, if you do wrong and go (live) the wrong way (to the right or to the left), you will hear a voice behind you saying, "This is the right way. You should go this way!"
