Deuteronomy 33:20

And of Gad he said, Blessed be he that enlargeth Gad; he dwelleth as a lion, and teareth the arm with the crown of the head.

And of Gad he said,.... The tribe of Gad, as the Targums of Jonathan and Jerusalem:

Blessed be he that enlargeth Gad; that is, the Lord, to whom the praise and glory were to be given, who had appointed to Gad a large inheritance on the other side Jordan, and had settled him in it, and which became larger by the conquest of the Hagarites, and others, 1 Chronicles 5:18;

he dwelleth as a lion; bold and courageous, secure, and without fear of any of his enemies, though near him, on his borders, as the Moabites and Ammonites were; of the same spirit and temper were the men of the tribe of Gad in the times of David, 1 Chronicles 12:8;

and teareth the arm with the crown of the head, at once, just as a lion tears its prey; which figurative phrases are expressive of this tribe conquering and destroying strong and mighty men, signified by the "arm", in which the strength of a man lies, and of kings and governors, pointed at by the "crown of the head"; as the Targums of Onkelos and Jonathan; which was done in the times of Joshua, when with and under him they subdued and destroyed the kings and princes of the land of Canaan.
