How to know if you are hearing the upright voices or listening to the upright things?

Here is how you know if it's the right thing? – Isaiah 30:19-21 KJV (It depends on what your dwelling on if it's the right meditation on The Holy Scriptures way or not.) - G.S.Notes

[19 #Step ]

For the people shall dwell in Zion at Jerusalem: thou shalt weep no more: he will be very gracious unto thee at the voice of thy cry; when he shall hear it, he will answer thee.

[20] 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:

[21] #Step 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.

Isaiah 30:19-21 (WEB)

19 For the people will dwell in Zion at Jerusalem. You will weep no more. He will surely be gracious to you at the voice of your cry. When he hears you, he will answer you. 20 Though the Lord may give you the bread of adversity and the water of affliction, yet your teachers won’t be hidden any more, but your eyes will see your teachers; 21 and when you turn to the right hand, and when you turn to the left, your ears will hear a voice behind you, saying, “This is the way. Walk in it.”
