Zebulun possessed a commodious sea-shore and the fisheries of the Lake of Tiberias: and was therefore to thrive by commerce, and to rejoice in his “going out,” i. e., in his mercantile enterprises. Issachar possessed a fertile inland district, and would therefore dwell at home and prosper in agriculture. Both tribes distinguished themselves in the contest with Jabin (compare Judges 5:14-15, Judges 5:18): and of Zebulun it is particularly noted that it produced the officers and tacticians who led and marshalled the host which vanquished Sisera (see Judges 5:14, and compare 1 Chronicles 12:33).
Unto the mountain - Compare Exodus 15:17.
Sacrifices of righteousness - Sacrifices offered in a righteous spirit, and therefore well pleasing to God (compare Psalms 4:5; Psalms 51:19).
Treasures hid in the sand - The riches of the seas in general. However, it is noteworthy that the sand of these coasts was especially valuable in the manufacture of glass; and glass was a precious thing in ancient times (compare Job 28:17). The murex from which the highly-prized purple dye was extracted, was also found here. A typical reference to the conversion of the Gentiles is strongly suggested by Isaiah 60:5-6, Isaiah 60:16; Isaiah 66:11-12.
