Commento su Zevahim 14:5

באו לגלגל – there wasn’t a Temple there, but rather just the curtains/tent-cloth of the Tabernacle of the wilderness.

When they came to Gilgal, bamot (local were [again] permitted. When the Israelites crossed the Jordan they came first to Gilgal and they set up the Tabernacle there. However, they didn’t set up camp around the Tabernacle, as they did in the desert. The Tabernacle contained an altar, but the ark was not inside it. At this point it became permitted to offer sacrifices elsewhere. Communal sacrifices and mandatory individual sacrifices (such as the hatat and the asham) were offered in the Tabernacle whereas voluntary individual offerings could be sacrificed at local altars.

הותרו הבמות – for the All-Merciful stated (Leviticus 17:3-4): [if anyone of the house of Israel] slaughters [an ox or sheep or goat] in the camp,…and does not bring it to the entrance of the Tent of Meeting,” excluding Gilgal, where there was [no longer] a camp there, for the camps were abolished and the people began to be scattered throughout the Land [of Canaan/Israel]. And for this reason, also, lesser Holy Things are eaten in any place, for there wasn’t there a camp like there was in the wilderness.

Most holy sacrifices were eaten within the curtains, and less holy sacrifices [were eaten] anywhere. The most holy sacrifices continued to be eaten within the Tabernacle’s curtains. Lesser sacrifices could now be eaten anywhere, since there was no official encampment.
