Leviticus 13:46

13:46 The Tabernacle containing the Ark was in the center of the camp so that God could be considered as being in the camp (Deut 23:14). As long as an individual’s skin disorder persisted, he or she was to stay in isolation . . . outside the camp. This ensured that the infection would not spread to others and that the uncleanness would not come in contact with holy things. Even Miriam, sister of Moses and Aaron, had to spend seven days outside the camp (Num 12:15). This area was not exclusive to those suffering from skin disorders. The uneaten sin offering was taken there and burned (Lev 4:21). Criminals were executed there (24:14, 23), and corpses were carried there to avoid contaminating the area where the people lived (10:4-5). Even bodily functions were attended to outside the camp (Deut 23:12-14).
