'Wild ox' in the Bible

From Egypt God brought them his strength was like a wild ox!

May the firstborn of his bull be honorable to him, and may his horns be those of a wild ox. With them may he push people all together, to the ends of the earth. These are the myriads of Ephraim and the thousands of Manasseh."

Is the wild ox willing to serve you? Will he sleep at night near your feeding trough?

He makes them stagger like a calf, even Lebanon and Sirion like a young wild ox.

You've grown my strength like the horn of a wild ox; I was anointed with fresh oil.
