That which either was not usually eaten, or was more than all of you could conveniently eat, ye shall burn with fire; to prevent either,
1. The superstitious use of the relics of that lamb by the Israelites, who thereby had received a greater benefit than they did afterwards by the brazen serpent, which upon that account they worshipped; or,
2. The profane abuse of that which had been consecrated to God's service. Compare Exodus 29:34.
