cousin, kin(-sfolk, -sman)

Concise Bible Dictionary:

Beside the common signification of this term for a male relative, it is used typically in reference to the Lord Jesus in His relationship with Israel. As their kinsman He has the right of redemption, and will undertake their cause in a future day, as Boaz did the cause of Naomi and Ruth (Ruth 2-4).
