see Jer 50:9; and these may be compared to "coals of juniper", which are very vehement and strong, and very lasting and durable. Jerom and Isidore say they will last a whole year; and the Midrash on the place reports of two men, who had prepared food with them, and at the end of a year returned and found them burning, and warmed their feet at them.
