Ruth 4:21-22

4:21 Salmon ¹  was the father of Boaz, Boaz was the father of Obed, 4:22 Obed was the father of Jesse, and Jesse was the father of David. ² 

Ruth 4:17

4:17 The neighbor women named him, saying, “A son has been born to Naomi.” They named him Obed. ³  Now he became the father of Jesse – David’s father!

[4:21]  ¹ sn Salmon appears to be an alternate spelling of Salmah in the preceding line.

[4:22]  ² sn The theological message of the Book of Ruth may be summarized as follows: God cares for needy people like Naomi and Ruth; he is their ally in this chaotic world. He richly rewards people like Ruth and Boaz who demonstrate sacrificial love and in so doing become his instruments in helping the needy. God’s rewards for those who sacrificially love others sometimes exceed their wildest imagination and transcend their lifetime.

[4:17]  ³ tn The name “Obed” means “one who serves,” perhaps anticipating how he would help Naomi (see v. 15).
