Deuteronomy 33:18

“Rejoice, Zebulun, in thy going out--on commercial enterprises and voyages by sea. and, Issachar in thy tents--preferring to reside in their maritime towns.”

“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). Deuteronomy 33:19 Unto the mountain - Compare Exodus 15:17. Sacrifices of righteousness - Sacrifices…”

“Rejoice - Thou shalt prosper and have cause of rejoicing. In thy going out - To war, as this phrase is often used. To sea, in way of traffick, because their portion lay near the sea.

“33:18 Zebulun and Issachar (NLT adds and Issachar for clarity) were the sixth and fifth sons of Jacob by Leah (Gen 30:18, 20). • in their travels . . . in their tents: This figure of speech (a merism) encompasses life in all its fullness for both tribes, from activity (travels) to inactivity (tents).”

“Gen 49:13-15; Jos 19:11; Jdg 5:14 Deuteronomy 33:19”

“Zebulun and Issachar. - "Rejoice, Zebulun, at thy going out; and, Issachar, at thy tents. Nations will they invite to the mountain; there offer the sacrifices of righteousness: for they suck the affluence of the seas, and the hidden treasures of the sand." The tribes of the last two sons of Leah Moses unites together, and, like Jacob in Gen 49:13, places Zebulun the younger first. He first of all confirms the blessing which Jacob pronounced through simply interpreting their names as omnia, by calling upon them to rejoice in their undertakings abroad and at home. "At thy tents" corresponds to "at thy going out" (tents being used poetically for dwellings, as in Deu 16:7); like "sitting" to…”
