'Fellowheirs' in the Bible

and if children, also heirs--heirs of God and fellow heirs with Christ, if indeed we suffer together [with him] so that we may also be glorified together [with him].

[that] the Gentiles are fellow heirs, and fellow members of the body, and fellow sharers of the promise in Christ Jesus through the gospel,

By faith he lived in the land of promise as a stranger, living in tents with Isaac and Jacob, the fellow heirs of the same promise.

Husbands, in the same way live with [your wives] {knowledgeably}, as with the weaker female vessel, showing [them] honor as fellow heirs also of the grace of life, so that your prayers will not be hindered.
