It seems that no one, or practically no one - I did just now find 6 hits on Google - gets that “He shall be Levon” = “He shall believe on”.
And he shall believe on
And he shall be a good man
And he shall believe on
In tradition with the family plan
And he shall believe on
And he shall be a good man
He shall believe on
Or does everybody actually get this and it is so obvious that no one thinks it’s worth mentioning?
