If the Shema Yisrael is the one I’m thinking of, here are the original words, as sung by Sarit Hadad:
Kshehalev boche rak Elokim shomea
Bitfila ktana chotech et hadmama
Shma israel Elokai ata hakol yachol
Natata li et chayai natata li hakol
Shma Israel Elokai achshav ani levad
Chazek oti Elokai ase shelo efchad
Kshehalev boche hazman omed milechet
El halo noda hu lo rotze lalechet
and here’s the translation:
When the heart cries only God hears
The pain rises from the soul
A man falls down before he sinks
He cuts the silence with a small prayer
Shma Israel, my God, you are the mighty one
You gave me my life you gave me everything
A tear in my eyes, the heart cries in silence
And when the heart is silent the soul cries out
Shma Israel, my God, I am all alone now
Make me strong, my God, so I will not be afraid
The pain is great and there is no where to run
When the heart cries time stands still
A man sees his life passing in front of him
He calls his God as he stands on the edge of the deep
