Ruth 1:1
In the days when the judges ruled, there was a famine in the land, and a man from Bethlehem in Judah, together with his wife and two sons, went to live for a while in the country of Moab.

Psalm 23

Ruth 1:13
It is more bitter for me than for you, because the LORD’s hand has gone out against me!”

Ruth 1:20
“Don’t call me Naomi,” she told them. “Call me Mara, because the Almighty has made my life very bitter. 21  I went away full, but the LORD has brought me back empty. Why call me Naomi? The LORD has afflicted me; the Almighty has brought misfortune upon me.”

Ruth 2:20
“The LORD bless him!” Naomi said to her daughter-in-law. “He has not stopped showing his kindness to the living and the dead.” She added, “That man is our close relative; he is one of our kinsman-redeemers.”

Ruth 1:16
But Ruth replied, “Don’t urge me to leave you or to turn back from you. Where you go I will go, and where you stay I will stay. Your people will be my people and your God my God. 17  Where you die I will die, and there I will be buried. May the LORD deal with me, be it ever so severely, if anything but death separates you and me.”

Ruth 2:2
And Ruth the Moabitess said to Naomi, “Let me go to the fields and pick up the leftover grain behind anyone in whose eyes I find favor.” Naomi said to her, “Go ahead, my daughter.”

Leviticus 19:9
“‘When you reap the harvest of your land, do not reap to the very edges of your field or gather the gleanings of your harvest. 10 Do not go over your vineyard a second time or pick up the grapes that have fallen. Leave them for the poor and the alien. I am the LORD your God.

Leviticus 19:9-10;  Leviticus 23:22; Deuteronomy 24:19

2 Thessalonians 3:10
For even when we were with you, we gave you this rule: “If a man will not work, he shall not eat.”

Ruth 2:7
She said, ‘Please let me glean and gather among the sheaves behind the harvesters.’ She went into the field and has worked steadily from morning till now, except for a short rest in the shelter.” …10 At this, she bowed down with her face to the ground. She exclaimed, “Why have I found such favor in your eyes that you notice me–a foreigner?”

Ruth 2:4
Just then Boaz arrived from Bethlehem and greeted the harvesters, “The LORD be with you!” “The LORD bless you!” they called back.

Ruth 2:8
So Boaz said to Ruth, …Stay here with my servant girls. 9 Watch the field where the men are harvesting, and follow along after the girls. I have told the men not to touch you. And whenever you are thirsty, go and get a drink from the water jars the men have filled.

14  At mealtime Boaz said to her, “Come over here. Have some bread and dip it in the wine vinegar.” When she sat down with the harvesters, he offered her some roasted grain. She ate all she wanted and had some left over. 15  As she got up to glean, Boaz gave orders to his men, “Even if she gathers among the sheaves, don’t embarrass her. 16  Rather, pull out some stalks for her from the bundles and leave them for her to pick up, and don’t rebuke her.”

Ruth 3:3
Wash and perfume yourself, and put on your best clothes. Then go down to the threshing floor, but don’t let him know you are there until he has finished eating and drinking. 4  When he lies down, note the place where he is lying. Then go and uncover his feet and lie down. He will tell you what to do.” 5  “I will do whatever you say,” Ruth answered. 6  So she went down to the threshing floor and did everything her mother-in-law told her to do.

Ruth 3:10
“The LORD bless you, my daughter,” he replied. “This kindness is greater than that which you showed earlier: You have not run after the younger men, whether rich or poor. 11 And now, my daughter, don’t be afraid. I will do for you all you ask. All my fellow townsmen know that you are a woman of noble character. 12 Although it is true that I am near of kin, there is a kinsman-redeemer nearer than I.

Matthew 1:5
Salmon the father of Boaz, whose mother was Rahab, Boaz the father of Obed, whose mother was Ruth, Obed the father of Jesse, 6 and Jesse the father of King David.

Jesus is coming

Titus 2:11
For the grace of God that brings salvation has appeared to all men. … 13 we wait for the blessed hope–the glorious appearing of our great God and Savior, Jesus Christ, 14 who gave himself for us to redeem us from all wickedness.
