Koine i know of a sleep

I know of a sleep in Jesus name, to rest.
The earth shall enfold me deep within her breast
I fear, I fear, I fear not what the world may say.
Through toil and woe, with music we’ve sung to the Lord
Sweet hymns of redemption “Jesus the Christ has won!”
Amen, Amen, sing Amen, so shall it be.
I know of a voice whose tender song I hear
“This child’s not dead, but sleeps in my heavenly bed.”
Arise, arise, arise my child arise.
Good bye my friend. We sing our refrain again
“Christ Jesus was slain. Christ Jesus was slain
“Christ Jesus was slain. Forever our friendship remains.”
