'Relative' in the Bible

Naomi said to her daughter-in-law, “May he be blessed of the Lord who has not ceased His kindness to the living and to the dead.” Again Naomi said to her, “The man is one of our closest relatives, one who has the right to redeem us.”

Now Boaz, with whose maids you were [working], is he not our relative? See now, he is winnowing barley at the threshing floor tonight.
