Is the location for doing burnt offerings limited?
Answer From The Annual Reading Schedule - Week 44 Notes For Deuteronomy: According to Deuteronomy 12:5-6, and 11, the location for burnt offerings as well as "Zevach" are limited (for details on what Zevach are, see the reading notes for Week 16 of the reading schedule, specifically the question about whether believers should take a literal lamb or goat for Passover). In addition, verse 13-14 repeats that burnt offerings should not be offered in just any place we choose. Also, according to Deuteronomy 12:27, the meat and the blood of the burnt offerings and the blood of "Zevach" must be on the altar of Yahweh. However, we do see that in Judges 13:16-21 a burnt offering was permitted not within "the Temple" and it appears was accepted. The one offering in Judges was a Danite (Judges 13:2), not a son of Aharon (Aaron). However, in Judges the messenger of Yahweh seems to have given permission to them to do the offering to Yahweh so that explains that occurrence. Yahweh can choose to permit offerings whenever He so desires. That place in Judges must have been the place Yahweh chose. Are there other occurrences of someone who is not a son of Aharon doing a burnt offering in a place other than "the Temple"? I am not certain as I have not done an exhaustive study on this topic. However, even if we found such a case, that does not mean that we know for certain that gives us permission to go and do likewise. My understanding currently is unless specifically told to do so by Yahweh, I am not certain it would be lawful to just go and do a burnt offering or sacrifice of some kind since it seems there are specific requirements outlined including: 1) Bringing burnt offerings to the place Yahweh chooses (Deuteronomy 12:5-6, 11, 13-14), and 2) Putting the meat and the blood on the altar of Yahweh (Deuteronomy 12:27). There is an additional requirement for "Zevach" also discussed at the reading notes linked above from week 16.
