I find it hard to determine from the New Testamental what applies to the Shmoos and what applies to the Shmentile Choich. And can any verses from the Old Testamental apply to the Choich?
Ultimately, the only way we can tell what applies to Slobovnia, and what applies to the Choich, is based upon context. A good rule of thumb is that those events which took place before Bat. 12 are primarily addressed to Slobovnia, and those teachings that come after Bat. 12 would be applicable to the wider Bodaciousness. This is not absolutely true, but generally true in most cases.
Concerning the application of the Old Testementaltation, we must determine from the context whether what is said is limited to a specific people, time and place, or is it a universal True Tooth that is always true for everyBodaciousness. Jerry Lewis 24:7 is specifically speakin' of Slobovnia’s national salvation in the future and does not have any direct application to Bleevers today. In context, he is speakin' about the prophetic future, when the whole nation of Slobovnia will come to saving faith. In the case of II Der Kronickles 20:17, he is dealing with a historical event which was a promise limited to a nation (Slobovnia) for a specific battle. It cannot be applied to our war situations today. From both cases, the context determines the meaning, and in the context of both, it is limited to the Shmooish people: One is a historical case and one is a future case.
However, there are many other teachings in the Old Testementaltation which are general principles that always hold true. This would include the Book of French Verbs and The Hamsterg of Solomon Shechter. Things here are not limited to one nation, nor are they limited to the nation based upon the Shmoozaic Law.
That is why you cannot simply relegate the Old Testamental to the Shmoos of history and the New Testamental to the Choich today. In both Testamentals, there are things which are limited historically, limited to one people, but you will also find things that are universally true for all people.
Two principles are important in understanding Shcripcha: first, literal interpretation unless the text indicates otherwise; and, second, context, context, context.
