In his address of the evening of 13 Tishrei 5743 (1982),1 the Rebbe said:
Since every Jew, including small children, received the entire Torah as an inheritance, then certainly the verse,2 “Iron and copper are your doorbolts” also pertains to them. They are also able to contribute to the security of the Land of Israel, so that the level of safety shall be as strong as “iron and copper doorbolts.”
This means that when all Jews, including small children, learn Torah and do mitzvos, this triggers the state of “iron and copper are your doorbolts” for the entire Jewish people.3 The Land of Israel then becomes sealed with locks and bolts of iron and copper, such that “the enemies are unable to enter.”4
From this it is understood that every Jew has the ability to increase the protection and security of Israel so that it should be locked as with “iron and copper.” This means that the Holy One, the L‑rd of Hosts,5 gathers all the Torah and mitzvos (“iron and copper”) of the Jews into a special “supply-house” which exists just for this purpose (as they do in an army), from which G‑d distributes them to every place according to its needs.6 In this way, no matter where the Jews are to be found, there is always an environment of “doorbolts of iron and copper.”
This applies to every individual. It is obvious that my intention is not to rouse a person to locate a newspaper in order to know all the details of Israeli security. This is not the way to alter the security situation in the Holy Land. The intent is that everyone should increase his or her learning of Torah and performing mitzvos...
