'Relative' in the Bible

Now Naomi had a relative on her husband's side of the family named Boaz. He was a wealthy, prominent man from the clan of Elimelech.

Naomi said to her daughter-in-law, "May he be rewarded by the Lord because he has shown loyalty to the living on behalf of the dead!" Then Naomi said to her, "This man is a close relative of ours; he is our guardian."

Now Boaz, with whose female servants you worked, is our close relative. Look, tonight he is winnowing barley at the threshing floor.

Now yes, it is true that I am a guardian, but there is another guardian who is a closer relative than I am.

Then Boaz said to the guardian, "Naomi, who has returned from the region of Moab, is selling the portion of land that belongs to our relative Elimelech.

Then Boaz said, "When you acquire the field from Naomi, you must also acquire Ruth the Moabite, the wife of our deceased relative, in order to preserve his family name by raising up a descendant who will inherit his property."
