Ruth 2:20; Ruth 3:13

20 And Naomi said unto her daughter in law, Blessed be he of the LORD, who hath not left off his kindness to the living and to the dead . And Naomi said unto her, The man is near of kin unto us, one of our next kinsmen .
13 Tarry this night, and it shall be in the morning, that if he will perform unto thee the part of a kinsman , well; let him do the kinsman's part : but if he will not do the part of a kinsman to thee, then will I do the part of a kinsman to thee, as the LORD liveth: lie down until the morning.
