Ruth (Hebrew: רוּת) was the wife and widow of Mahlon and then the wife of Boaz and the mother of Boaz's son Obed.
Ruth was a Moabite, and the Israelite couple Elimelech and Naomi moved to Moab and lived among them. Elimelech's and Naomi's son Mahlon married Ruth, while Elimelech's and Naomi's other son Chilion married Orpah. Elimelech and then Mahlon and Chilion died, leaving Naomi, Ruth, and Orpah as widows.
Naomi learned that God had blessed Judah with more food and decided to return to Judah. Ruth and Orpah began to follow Naomi, but Naomi told them to remain in their homeland and their mothers and asked God to bless them. However, they insisted on going with her. Naomi then explained that she did not have anything more to provide them with and that they were better off remaining in Moab.
Orpah decided to take Naomi's advice and kissed her good-bye. Ruth, however, remained adamant; she was going to remain with Naomi no matter what.
Do not urge me to leave you or to turn back from following you; for where you go, I will go, and where you lodge, I will lodge. Your people will be my people, and your God, my God. Where you die, I will die, and there I will be buried. May the Lord do the same to me [as He has done to you], and more also, if anything but death separates me from you.— Ruth 1:16–1:17 (AMP)
Naomi understood Ruth's loyalty and determination and allowed her to follow her to Judah.
They arrived in Judah, and Ruth asked Naomi for permission to glean leftover grain from a field after the farmer finished harvesting from it, and Naomi permitted her to do it. Ruth went to glean from a plot of land being to Boaz, a relative of Naomi's deceased husband. Boaz noticed her and showed kindness to her and asked God to bless her. Ruth asked Boaz why he was showing such kindness to a foreigner, and Boaz stated that it was due to the commitment Ruth showed to Naomi.
I have been made fully aware of everything that you have done for your mother-in-law since the death of your husband, and how you have left your father and mother and the land of your birth, and have come to a people that you did not know before. May the Lord repay you for your kindness, and may your reward be full from the Lord, the God of Israel, under whose wings you have come to take refuge.— Ruth 2:11–2:12 (AMP)
Ruth shared some of the bread with Naomi and told Naomi about Boaz. Naomi asked God to bless Boaz and told Ruth that Boaz can help them as a close relative. Naomi advised Ruth to have Boaz propose a marriage with her.
My daughter [Ruth], shall I not look for security and a home for you, so that it may be well with you? Now Boaz, with whose maids you were [working], is he not our relative? See now, he is winnowing barley at the threshing floor tonight. So wash and anoint yourself [with olive oil], then put on your [best] clothes, and go down to the threshing floor; but stay out of the man’s sight until he has finished eating and drinking. When he lies down, notice the place where he is lying, and go and uncover his feet and lie down. Then he will tell you what to do.— Ruth 3:1–3:4 (AMP)
Ruth did as Naomi told her, and when Boaz discovered her at his feet and asked what she was doing, she proposed a marriage with him.Boaz accepted and asked God to bless her. He was impressed that she approached an older gentlemen instead of a younger man. Boaz also invited her to spend the night in his house.
May you [Ruth] be blessed by the Lord, my daughter. You have made your last kindness better than the first; for you have not gone after young men, whether poor or rich. Now, my daughter, do not be afraid. I will do for you whatever you ask, since all my people in the city know that you are a woman of excellence. It is true that I am your close relative and redeemer; however, there is a relative closer [to you] than I. Spend the night [here], and in the morning if he will redeem you, fine; let him do it. But if he does not wish to redeem you, then, as the Lord lives, I will redeem you. Lie down until the morning.— Ruth 3:10–3:13 (AMP)
They woke up early in the morning. Boaz gave Ruth barley, and Ruth returned to Naomi.
Boaz was able to obtain the right to redeem the land belonging to Naomi's deceased husband Elimelech from a closer relative of Elimelech due to said relative's reluctant to marry a Moabite. Thus, Boaz now had the right to redeem the land and marry Ruth. The people bore witness to the agreement, and they asked God to bless the marriage between Boaz and Ruth.
We are witnesses. May the Lord make the woman who is coming into your house like Rachel and Leah, the two who built the household of Israel. May you achieve wealth and power in Ephrathah and become famous in Bethlehem. Further, may your house be like the house of Perez whom Tamar bore to Judah, because of the offspring which the Lord will give you by this young woman.— Ruth 4:11–4:12 (AMP)
Boaz married Ruth, and they conceived. Ruth then gave birth to Obed, giving Naomi and Naomi's deceased husband an grandson and heir in accordance with Israelite law.
Obed would become the grandfather of King David.
