Syntax of くびきを共にする


In the book 数学ガール ガロア理論, the phrase くびきを共にする, which I would infer means
something like "to yoke together", appears repeatedly as a metaphor for
phenomena where a number of elements are related.

Some google hits for the phrase can be found in a religious context (e.g.
イエス様とくびきを共にする "Be joined to Jesus (as with a yoke)").

But why is くびき the object in this phrase? I would expect くびき to be the
instrument or means of yoking (the yoke itself) rather than an object.




Are you confused because you think 「食事を共にする」 is the same as 「共に食事する」?

「食事を共にする」 is [to share] [meal], not [to eat] [together].

This is more obvious in phrases like 「運命を共にする」「生死を共にする」, where 運命 and 生死 are
clearly not verbs. (You don't say 運命する or 生死する)

So 「くびきを共にする」 is [to share] [a yoke].
