The land of Gilead, on the east of Jordan, was divided between Gad and the half tribe of Manasseh, who are both comprehended here. Joppa was in the territory of Daniel Joshua 19:46, and was in later times the sea-port for Jerusalem.
His breaches - Rather havens; i. e. the creeks and bays and river-months by which their coast was broken. Joshua 19:29.

Gilead abode beyond Jordan - That is, the Gadites, who had their lot in those parts, and could not well come to the aid of their brethren at a short summons. But the words of Deborah imply a criminal neglect on the part of the Danites; they were intent upon their traffic, and trusted in their ships. Joppa was one of their sea-ports.
Asher continued on the seashore - The lot of Asher extended along the Mediterranean Sea; and being contiguous to Zebulun and Naphtali, they might have easily succoured their brethren; but they had the pretense that their posts were unguarded, and they abode in their breaches, in order to defend them.

(n) Gilead abode beyond Jordan: and why did Daniel remain in ships? Asher continued on the sea shore, and abode in his (o) breaches.
(n) She reproves all those who did not come to help their brethren in their time of need.
(o) Either by hearing of the sea, or by mining,

Gilead abode beyond Jordan,.... A country which lay on the other side Jordan, and was given by Moses, half of it to the tribes of Reuben and Gad, and the other half to the half tribe of Manasseh, Deuteronomy 3:12 and being here distinguished from Reuben, it seems that not only that tribe, but also the tribe of Gad, and the half tribe of Manasseh, on that side Jordan, came not to the help of Israel; but abode where they were, attending their flocks and herds, and preferring their own private profit to the public good; yet as Gilead was given to Machir, Deuteronomy 3:15 and some are said to come out from thence to serve in this expedition, Judges 5:14 some read the words, as Kimchi observes, with an interrogation, "did Gilead abide beyond Jordan?" no, he did not; though his situation was beyond it, as well as Reuben's, yet he did not continue there, but came over to help his brethren; and so this is introduced to upbraid Reuben, and leave him without excuse, since he could as well have left his flocks as Gilead did, and come over to the help of his brethren as well as he:
and why did Daniel remain in ships? the Danites inhabiting Joppa, and other places bordering on the Mediterranean sea, attended their navigation and merchandise; and which they chose rather to do, than to appear in the field of battle in the behalf of their brethren; judging this to be a sufficient excuse, though the question put implies the contrary; according to the Targum, they were meditating a flight, and put their goods into ships to flee with them, should Sisera get the day:
Asher continued on the sea shore; on the shore of the Mediterranean sea, attending traffic and business, and did not concern themselves at all in this war:
and abode in his trenches; in his towns and cities, the walls of which had been broken down by the Canaanites, and remained unrepaired, nor were they suffered to repair them; and therefore excused themselves on this account from engaging in the war, being obliged to stay at home to keep and defend their cities; which were in such a ruinous and weak condition, that the enemy might enter at any time: some render it, "in their creeks" (i) bays and havens where they had much shipping, and which required their attendance.
(i) "in portubus", V. L. "ad sinus suos", some in Vatablus.

Gilead abode beyond Jordan--that is, Both Gad and the eastern half to Manasseh chose to dwell at ease in their Havoth-jair, or "villages of tents," while Daniel and Asher, both maritime tribes, continued with their ships and in their "breaches" ("havens"). The mention of these craven tribes (Judges 5:18) is concluded with a fresh burst of commendation on Zebulun and Naphtali.

Gilead, Daniel, and Asher took no part at all. By Gilead, the tribes of Gad and half Manasseh are intended. The use of the term הגּלעד to denote the whole of the territory of the Israelites on the east of the Jordan probably gave occasion to this, although גלעד (without the article) does not refer to the land even here, but refers primarily to the grandson of Manasseh, as the representative of his family which dwelt in Gilead. (For further remarks, see at Judges 5:14.) Daniel also did not let the national movement disturb it in its earthly trade and commerce. גּוּר, to keep one's self in a place, is construed here with the accusative of the place, as in Psalm 120:5. The territory of Daniel included the port of Joppa (see at Joshua 19:46), where the Danites probably carried on a trade with the Phoenicians. Asher also in his land upon the coast did not allow himself to be disturbed from his rest, to join in the common war of its nation. ימּים חוף is used, as in Genesis 49:13, for the shore of the Mediterranean Sea. מפרצים, ἁπ. λεγ., literally a rent, and hence applied to a bay, as an incision made in the sea-shore.

Gilead - Sometimes taken strictly for that part of the land beyond Jordan which fell to the half - tribe of Manasseh, and sometimes both for that part of Manasseh's, and for Gad's portion, as Joshua 13:24-25, Joshua 13:29-31, and so it seems to be understood here; and the land Gilead is here put for the people or inhabitants of it, Gad and Manasseh. Beyond Jordan - In their own portions, and did not come over Jordan to the help of the Lord, and of his people, as they ought to have done. In ships - Daniel, whose coast was near the sea, was wholly intent upon his merchandise, and therefore could not join in this land expedition. Sea - shore - Where their lot lay. His breaches - Either in the creeks of the sea, or, in their broken and craggy rocks and caves.
