Radak
גד גדוד יגודנו, if a troop, battalion attacks him he will overpower that troop. This is the meaning of the last words in the verse והוא יגד עקב, in the end (עקב) he will prevail. This is a specific reference by Yaakov to what we have been told in Chronicles I 5,18-22 in which this tribe (together with Reuven and half the tribe of Menashe) is described as waging a successful war against the Hagrites. Their victory, -apparently they had been attacked,- is credited to the fact that they implored G’d to help them, and had faith that He would help them. Their trust was justified as is evident from the amount of loot they captured after that battle, Subsequent to that battle they remained undisturbed until their exile, about 150 years before the destruction of the Temple in Jerusalem.
