16Every grain offering of a priest shall be a whole offering; it may not be eaten.Purification Offerings. [C][6:17–23] There are two types of purification offering: one whose blood is used inside the tent sanctuary (4:1–12, 13–21) and another whose blood was only used at the outer sacrificial altar (4:22–26, 27–31, 32–35). The carcasses of the former, as well as of purification offerings brought by the priests themselves (cf. 8:14–17; 9:8–11), are not eaten by priests but disposed of at the ash heap outside the camp, which itself is set up around the sanctuary (Ex 29:14; Lv 4:11–12, 21; 6:23; 8:17; 9:11; 16:27). The Letter to the Hebrews compares Jesus’ suffering “outside the gate” to the disposal of purification offering carcasses outside the camp (Heb 13:11–13).
