I.e., "grained apple" (pomum granatum), Hebrews rimmon. Common in Egypt (Numbers 20:5) and Palestine (13:23; Deuteronomy 8:8). The Romans called it Punicum malum, i.e., Carthaginian apple, because they received it from Carthage. It belongs to the myrtle family of trees. The withering of the pomegranate tree is mentioned among the judgments of God (Joel 1:12). It is frequently mentioned in the Song of Solomon (Cant. 4:3, 13, etc.). The skirt of the high priest's blue robe and ephod was adorned with the representation of pomegranates, alternating with golden bells (Exodus 28:33, 34), as also were the "chapiters upon the two pillars" (1 Kings 7:20) which "stood before the house."
