Is there any reason to be buried on Har Hazeisim over anywhere else in Eretz Yisrael?
The Gemara (Kesubos 111) writes that those buried in Israel will rise first at the time of the resurrection, whereas those buried elsewhere will have to travel through subterranean tunnels in order to reach Israel before they will be resurrected. This “travel” is said (in the Talmud) to involve strain and discomfort, and in order to avoid it many prefer to be buried in Israel.
The Gemara also writes that Interment in Israel atones for one’s sins, which is perhaps the main reason why people choose to be buried in Israel. This reason is cited by the Shach as sufficient cause for a person’s remains to be transferred from outside Israel to Israel, though under ordinary circumstances it is forbidden to disinter a person’s remains and relocate them (See Shulchan Aruch, Yoreh De’ah 363:1 and Shach 3).
