Targum do Rodzaju 49:19

The tribe of Gad with the rest of the tribes will, armed, pass over the streams of Arnona and subdue before them the pillars of the earth, and armed will they return into their limits with much substance and dwell in peace beyond the passage of Jardena; for so will they choose, and it shall be to them to receive their inheritance.

From the house of GAD will go forth hosts arrayed in arms. They will bring Israel over Jardena put them in possession of the land of Kenaan, and afterwards return in peace to their tabernacles.
