Looking for the lyrics of "The Lord is my True Shepherd"

Had this sudden longing to sing the song we used to sing in high school, kept singing and trying to recall the lyrics but failed. Texted a friend and classmate in high school for help, but sent me a song with the same title but different lyrics...

Anyone? Please help!  Just want to teach the song to my grandkids. 

The Lord is my shepherd

The Lord is my true shepherd

He is Lord and I’m His guest

He guides me on the safe path

Where He leads me to my rest.

Chorus:
If I should ever walk,

     in this valley of darkness

No evil would I fear,

    You are there to show the way.

Surely goodness and kindness 

     will cheer up my cheerless heart

He cools my head with oil,

       ………………………………………..

Repeat Chorus
