Here is my correction of the lyrics from above, after I listened to the recording by The Isaacs. Note that the lullaby is in Yiddish, not Hebrew. I can't hear it well enough to transcribe it, but it's something like "Zay ruh, shlof mayn kind." (be still, sleep my child)

MESSIAH LULLABY
(as recorded by The Isaacs)

Softly she whispered
I've been expecting you
And not only me
But the whole world's been waiting, too
The only hope
For fallen men
Is there in your tiny hands
Close your eyes
Prince of Peace

She sang the Messiah Lullaby
Messiah Lullaby
Welcoming the New Born King
Messiah Lullaby

Angels in Heaven
Silently watched over earth
Adoring the sight
Of the one who had given them birth
Creation longed to sing back to Him
The song He had given them
But on this night
All was quiet

She sang the Messiah Lullaby
Messiah Lullaby
Welcoming the New Born King
Messiah Lullaby


[part below needs correction]
Chorus again... a cappella
Zay denn ruh, shlaf mayn Kind
Zay denn ruh, shlaf gesind (healthy)
Zay denn ruh, xxxkeit
Mamme is hier bevor
