1 If, in the land that Hashem your God is assigning you to possess, someone slain is found lying in the open, the identity of the slayer not being known,

21:1 In the land that Hashem your God is assigning you
The axed heifer is one of the few biblical commandments that can be performed only in Eretz Yisrael even though it is not an agricultural law. Rabbi Joseph B. Soloveitchik explains that the reason for this is that this law is incumbent on the ‘Congregation of Israel,’ not on individual members of the nation, and the Israelites are only considered the ‘Congregation of Israel’ when residing in their land. This highlights the centrality of the Land of Israel to the People of Israel: They are considered the Congregation of Israel in every sense of the term only when they live in their land. The ability to fulfill national biblical commands such as this is one of the reasons it is so important for Jews from all over the world to come on aliya, to move to Israel.
