Zevachim 117B

וחובות שקבוע להן זמן.

and compulsory public offerings that have a set time to be sacrificed, e.g., daily offerings and additional offerings. Public offerings that do not have a set time were not sacrificed upon the great public altar in Gilgal.

מאי טעמא דרבי מאיר? דאמר קרא: ״לא תעשון ככל אשר אנחנו עשים פה היום״⁠ –

§ The Talmud explains the various opinions cited in the baraita: What is the reason for the opinion of R' Meir that only vow offerings and gift offerings, such as nazirite offerings and meal offerings, were sacrificed upon a private altar during the period of Gilgal? It is as the verse states: “You should not do all that we do here this day, every man whatsoever is fitting in his own eyes. For you have not as yet come to the rest and to the inheritance” (Deuteronomy 12:8–9).

אמר להן משה לישראל: כי עייליתו לארץ ישראל ⁠– ישרות תקריבו, חובות לא תקריבו. מנחות ונזירות ⁠– ישרות נינהו.

Moses said the following to the Jewish people: When you enter Eretz Yisrael but have not yet arrived at Shiloh or Jerusalem and are therefore permitted to sacrifice upon private altars, you may not sacrifice whatever has been sacrificed in the wilderness, i.e., both obligatory offerings and gift offerings. Rather, the phrase “every man whatsoever is fitting [hayashar] in his own eyes,” means that fitting offerings [yesharot], i.e., offerings that are fitting in one’s eyes and are brought due to one’s own benevolence, you may sacrifice, but you may not sacrifice obligatory offerings. Meal offerings and offerings of a nazirite are included in the category of fitting offerings: Meal offerings are sacrificed as vow offerings or gift offerings while offerings of a nazirite are considered a vow offering, as becoming a nazirite is not compulsory.
