Or do you think the scripture says in vain ... jealous"?

This is a rhetorical question James uses to exhort his audience. To speak in vain is to speak uselessly. Alternate translation: "There is a reason that scripture says ... jealous.'" (See: rc://en/ta/man/translate/figs-rquestion)

The Spirit he caused to live in us

Some versions, including the ULB and UDB, understand this as a reference to the Holy Spirit. Other versions translate this as "the spirit" and mean by it the human spirit that each person has been created to have. We suggest that you use the meaning that is presented in other translations used by your readers.
