Deuteronomy 33:20

20.And of Gad he said. In the blessing of the tribe of Gad, mention is only made of the hereditary portion, which it had obtained without casting of lots. He therefore celebrates the blessing of God, because He had accorded to the Gadites an ample dwelling-place; for the word “enlargeth” refers to the extent of their possession. But inasmuch as in that extremity of the land beyond Jordan, they were on a hostile border, he declares that they would be warlike, and hence compares them to a lion, which tears its prey sometimes from the head, and sometimes from the arm. Since, then, that position would not be so peaceful as any other region in the midst of Canaan, he declares that they should be safe and sound, through their own audacity. And although it is not a very pleasant condition to be harassed by constant wars, still, in such a disagreeable case, God’s grace was not to be despised, which made them formidable to their enemies, and of great valor, whereby they might not only repel hostile invasions, but be willing of themselves to make predatory expeditions. If any should object that license for rapine was quite unsuitable for God’s children, the solution is obvious, that reference is not here made to what was lawful, or what was desirable and praiseworthy, but that a consolation was offered them by way of protection against the incursions and annoyances of their enemies. Besides, the lust for booty is not made permissible, but praise is merely given to their courage in overcoming their enemies.
