Moses continues to bless the tribes of Israel; the blessings are short poems. He continues to describe the tribe of Joseph, which he began to do in [Deuteronomy 33:13](./13.md). (See: [[rc://en/ta/man/translate/figs-parallelism]])
The ox is a metaphor for something large and strong. The word "firstborn" is a metaphor for honor. Alternate translation: "People will honor Joseph's descendants, who are many and powerful" (See: [[rc://en/ta/man/translate/figs-metaphor]])
Pushing with his horns is a metaphor for strength. Alternate translation: "He is so strong that he will push" (See: [[rc://en/ta/man/translate/figs-metaphor]])
This means the tribe of Ephraim will be stronger than the tribe of Manasseh. Alternate translation: "the people of Ephraim, who number many times 10,000 ... the people of Manasseh, who number many times 1,000" (See: [[rc://en/ta/man/translate/translate-numbers]])
