Ruth 4: 13 - 17: So Boaz took Ruth, and she was his wife: and when he went in unto her, the LORD gave her conception, and she bare a son. And the women said unto Naomi, Blessed be the LORD, which hath not left thee this day without a kinsman, that his name may be famous in Israel. And he shall be unto thee a restorer of thy life, and a nourisher of thine old age: for thy daughter in law, which loveth thee, which is better to thee than seven sons, hath born him. And Naomi took the child, and laid it in her bosom, and became nurse unto it. And the women her neighbours gave it a name, saying, There is a son born to Naomi; and they called his name Obed: he is the father of Jesse, the father of David.
Obed was the fruit of the union between Boaz and Ruth.
Boaz was of the family of Elimelech.
Elimelech and his family (his two sons Mahlon and Chilion) died so that Naomi (Elimelech’s wife) alone remained.
The birth of Obed represented the resurrection of Elimelech and his family that had died.
The spiritual union between Christ (Boaz) and His Bride (Ruth) will bring forth the resurrection of the New Testament saints.
