Concise Bible Dictionary:

Pomegranate in Fruit
This tree and its fruit are often referred to, though it is rather a shrub. It is named among the vines and fig trees as of the products of Palestine. The fruit is as large as an apple. It was represented alternately with bells, at the bottom of the high priest’s robe, as a type of fruitfulness, and was copied as an ornament on the columns of Solomon’s temple. The temples, or cheeks, of the bride in the Song of Solomon are compared to “a piece of a pomegranate” (Song of Sol. 4:3; Song of Sol. 6:7). Spiced wine was made of its juice (Song of Sol. 8:2; Ex. 39:24-26; Num. 20:5; Deut. 8:8; 1 Kings 7:18,42; Jer. 52:22-23; Joel 1:12; Hag. 2:19). It is the Punica granatum, which both wild and cultivated still grows in Palestine, and is highly valued.
