There is a song by Damian Marley that refers to "The sleeping sons of Jacob".
I looked up 'Sons of Jacob' on Wikipedia and now understand them to represent the 12 tribes of Israel.
I am also curious to know what the significance of "Sleeping" may mean, if anything. For the sake of clarity, I have only heard "sleeping" sons of Jacob in the Damian Marley song. (Is there a passage that uses the phrase "The sleeping sons of Jacob" in the Bible?)
Here's an example of the "sons of Jacob" that might refer to a larger group than just Jews:
You who fear the Lord, praise Him!
All you offspring of Jacob, honor Him!
Be in dread of Him, all you offspring of Israel!—Psalm 22:24 (NJPS)
Is it possible to read "offspring of Jacob" as "spiritual offspring"?
