Deuteronomy 33:13-17

Comparing the words of Moses with those of Jacob, it will be seen that the patriarch dwells with emphasis on the severe conflicts which Joseph, i. e., Ephraim and Manasseh, would undergo (compare Genesis 49:23); while the lawgiver seems to look beyond, and to behold the two triumphant and established in their power.

Deuteronomy 33:17

Rather: “The first-born of his” (i. e. Joseph’s) “bullock is his glory”: the reference being to Ephraim, who was raised by Jacob to the honors of the firstborn (Genesis 48:20, and is here likened to the firstling of Joseph’s oxen, i. e., of Joseph’s offspring. The ox is a common emblem of power and strength.
