"Blessed is He that broadens Gad": We are hereby taught that the territory of Gad broadened out eastwards.
"As a lion he dwells": We are hereby taught that he dwelt near the border, (border dwellers requiring strong defenders to repel invaders), wherefore he is compared to a lion.
"and he tore the arm" — in the past. "together with the crown": in time to come.
"And he saw first (in the land of Eretz Yisrael) for himself": He came first in the beginning, and he will come first in time to come.
"For there the (burial) plot of the lawgiver is hidden": This refers to the burial plot of Moses, which is found in the territory of Gad. Moses died in the territory of Reuven, viz. (Devarim 32:49) "Go up, (Moses,) to this Mount Avarim, Mount Nevo." What, then, is the intent of "For there (in the territory of Gad) the (burial) plot of the lawgiver is hidden"? We are hereby taught that Moses was lying dead in the wings of the Shechinah four mils between the territory of Reuven and the territory of Gad, and the ministering angels were eulogizing him saying "Let him come in first and rest in his plot." And this (the plot) is one of the things that was created on Sabbath eve at twilight: the rainbow, the manna, the well (of Miriam), the writ (in the Torah) and the writing (on the tablets), the tablets, the mouth of the ass (of Bilam), the burial plot of Moses, the cave in which Moses and Elijah stood, the staff of Aaron, its almonds and flowers. Some say, also the vestments of Adam, and some, also the demons. R. Yashia says in the name of his father, also the ram (of Abraham) and the shamir (a rare worm). R. Nechemiah says, also the flame and the mule. R. Yehudah says, also the tongs. If you need tongs to make tongs, then who made the first pair? You must say that it was an independent creation (by G-d). This was countered: No, it can be set in a mold and fashioned (at once) within it — so that it is not an independent creation!
