Or HaChaim on Deuteronomy 33:17/אור החיים על דברים ל״ג:י״ז

1 בכר שורו הדר לו, "Like a firstling bull in his majesty, etc." Here Moses blessed two outstanding individuals who were descended from Joseph. Concerning his first born son Menashe, Moses said the words בכר שורו are a reference to Gideon. The reason he chose the simile of the bull is because of what the angel said to Gideon (Judges 6,28) "take the bull which belongs to your father, and take the second bull which is seven years old and destroy the altar of the Baal belonging to your father, etc. and offer ….it as a burnt offering." The הדר, "spiritual beauty," Moses speaks about is that Gideon needed only 300 men to defeat the Midianites, as all these men were of spiritually outstanding quality. Such success reflects favourably on the leader, hence הדר לו, it is a compliment for him.

2וקרני ראם קרניו, "he has thorns like the horns of the wild-ox." This is a reference to Joshua, a descendant of Joseph's younger son Ephrayim. His reputation was world-wide, "his horn" comparable to the horn of the wild-ox.

3בהם עמים ינגח, "with them he gores nations." When the kings of the Emorites heard that G'd was with Joshua they no longer had any fighting spirit and could not offer Joshua resistance.

4The reason that Moses repeats that he speaks of both the myriads of Ephrayim and those of Menashe is because both blessings were meant for both these tribes. Although Moses mentioned Menashe first, the blessing extended to that tribe was of somewhat lesser range than that for Ephrayim. Moses followed the pattern of giving his blessings in an ascending order. When giving details of the blessings he mentioned Ephrayim first as he received the major blessing.
