The book of Ruth begins with context regarding Naomi and Ruth's current situation; it tells of tragedy striking amongst the house of Elimelech as he and his two sons die leaving Naomi as the sole member of their family - not including her daughters in law by marriage, Ruth and Orpah.
"God sovereignly orchestrates all things - even trials - for the good of His people, who He will one day redeem through the perfect rule of the kinsman king (Christ.)" -CHBC Old Testament Overview.
This story takes place during the book of Judges which is an important detail as the king that Israel desires and would one day receive, king David, is born of the line of Ruth - God is preparing his people for the rule of David who is a human foreshadowing of Christ.
It is mentioned that Ruth and Orpah are Moabites which reveals the fact that they worshipped pagan gods by culture and eventually highlights the Lord's redemption in the life of Ruth. This also highlights the fact that God doesn’t just save the Jews, His love for those He has called to be His own knows no discrimination.
"Go, return each of you to her mother's house. May the Lord deal kindly with you, as you have dealt with the dead and with me. The Lord grant that you may find rest, each of you in the house of her husband!" Naomi encourages her daughters in law to return to their mothers homes with the intention of them getting re-married and having a second shot at a home of their own - She wishes that they might have the security and stability that comes with raising a family.
“Do not urge me to leave you or to return from following you. For where you go I will go, and where you lodge I will lodge. Your people shall be my people, and your God my God. Where you die I will die, and there will I be buried. May the LORD do so to me and more also if anything but death parts me from you.” Ruth was faithful to remain with her mother in law - this was a picture of loyalty and an expression of trust in Naomi’s God (Christ). Ruth binds herself by oath to Yahweh, embracing Him now as her God.
Naomi means pleasant while Mara means bitter - Naomi sees her testimony as proof that God has condemned her in some way as she has returned to Judah empty (without her family) and feeling as if God has forsaken her. Little does she know that her troubles will ultimately lead to a beautiful depiction of the Lord’s faithfulness in the lives of His children.
The verbiage used in chapter two surrounding Boaz is incredibly intentional to reveal the Godly character he possesses. He is intentional to protect Ruth even as they are barely acquainted and he genuinely owes her nothing. (Girls literally picking up scraps in his field and he is kind and merciful to her.) What a sweet picture of how kind and merciful God is to us even though He owes us NOTHING.
Naomi blesses the Lord when Ruth tells her of Boaz' kindness - God is using this situation to redeem them. "May he be blessed by the Lord, whose kindness has not forsaken the living or the dead!" the latter part of the statement is not clearly in reference to Boaz or the Lord which MAY mean it is a general statement regarding both of them. The Lord's kindness and Boaz's Christlikeness are both shown in this situation.
