I.e., the Dead Sea. The good land is situated between the waters of the Mediterranean Sea on the west (v. 15) and the waters of the Dead Sea and the Jordan River on the east. For the land of Canaan, an elevated land (Ezek. 20:40-42; 34:13-14; 37:22; Deut. 32:13), to be surrounded by water indicates that it is surrounded by death. Thus, the good land typifies the resurrected Christ, who was raised, elevated, from the dead (cf. Gen. 1:9). See note Num. 34:121.
On the north side of the good land there is no river as a border; instead, there is Mount Hermon, a high mountain, which signifies the heavens, from which the dew descends (Psa. 133:3). The elevated good land with Mount Hermon signifies the resurrected Christ, who has ascended to the heavens.
