'Relative' in the Bible

Now Naomi had a relative on her husband’s side named Boaz. He was a prominent man of noble character from Elimelech’s family.

Then Naomi said to her daughter-in-law, “May he be blessed by the Lord, who has not forsaken his kindness to the living or the dead.” Naomi continued, “The man is a close relative. He is one of our family redeemers.”

Now isn’t Boaz our relative? Haven’t you been working with his female servants? This evening he will be winnowing barley on the threshing floor.
