The sixth aliyah begins with the Jews expressing to Moshe their fear of dying by mistakenly coming too close to the Mishkan. G-d then commands Aharon and his sons and the Levites to guard against any such mishap by carefully guarding the Mishkan from any common people approaching too close. After that G-d enumerates what Rashi calls the 24 gifts of the priesthood. These include the privilege of eating of the sacrifices the Jewish people bring as well as receiving the five shekels that Jews use to redeem their first-born sons in a Pidyon-haben ceremony. The aliyah ends with G-d stating that the Kohanim won't receive a portion of the land of Israel like the other Jews, instead G-d says that He is their portion.
