1 Then went Boaz up to the gate, and sat him down there: and, behold, the kinsman of whom Boaz spake came by; unto whom he said, Ho, such a one! turn aside, sit down here. And he turned aside, and sat down. 2 And he took ten men of the elders of the city, and said, Sit ye down here. And they sat down. 3 And he said unto the kinsman, Naomi, that is come again out of the country of Moab, selleth a parcel of land, which was our brother Elimelech's: 4 And I thought to advertise thee, saying, Buy it before the inhabitants, and before the elders of my people. If thou wilt redeem it, redeem it: but if thou wilt not redeem it, then tell me, that I may know: for there is none to redeem it beside thee; and I am after thee. And he said, I will redeem it. 5 Then said Boaz, What day thou buyest the field of the hand of Naomi, thou must buy it also of Ruth the Moabitess, the wife of the dead, to raise up the name of the dead upon his inheritance. 6 And the kinsman said, I cannot redeem it for myself, lest I mar mine own inheritance: redeem thou my right to thyself; for I cannot redeem it. 7 Now this was the manner in former time in Israel concerning redeeming and concerning changing, for to confirm all things; a man plucked off his shoe, and gave it to his neighbour: and this was a testimony in Israel. 8 Therefore the kinsman said unto Boaz, Buy it for thee. So he drew off his shoe. 9 And Boaz said unto the elders, and unto all the people, Ye are witnesses this day, that I have bought all that was Elimelech's, and all that was Chilion's and Mahlon's, of the hand of Naomi. 10 Moreover Ruth the Moabitess, the wife of Mahlon, have I purchased to be my wife, to raise up the name of the dead upon his inheritance, that the name of the dead be not cut off from among his brethren, and from the gate of his place: ye are witnesses this day. 11 And all the people that were in the gate, and the elders, said, We are witnesses. The LORD make the woman that is come into thine house like Rachel and like Leah, which two did build the house of Israel: and do thou worthily in Ephratah, and be famous in Bethlehem: 12 And let thy house be like the house of Pharez, whom Tamar bare unto Judah, of the seed which the LORD shall give thee of this young woman. 13 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. 14 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. 15 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. 16 And Naomi took the child, and laid it in her bosom, and became nurse unto it. 17 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. 18 Now these are the generations of Pharez: Pharez begat Hezron, 19 And Hezron begat Ram, and Ram begat Amminadab, 20 And Amminadab begat Nahshon, and Nahshon begat Salmon, 21 And Salmon begat Boaz, and Boaz begat Obed, 22 And Obed begat Jesse, and Jesse begat David.
[AD 458] Theodoret of Cyrus on Ruth 4:1-6
The man was so virtuous that he did not rush into a marriage outside the law, but he spoke with his neighbors about the marriage. However, his words are also worthy of admiration. For his first words were not about the marriage but about the possession of fields, etc. Moreover, when, on account of the prospective marriage he [the relative] in fact refused the contract for the land and indeed took off his sandal and gave it to Boaz, in accordance with the law, Boaz then took Ruth to be his wife. Furthermore, because he was not serving lust, he took her in the spirit that one should take a wife, and his words also showed themselves worthy of praise, You are witnesses today, etc. “I do not,” he said, “transgress the law in marrying a Moabite woman; rather, I diligently fulfill divine law, so that the memory of the dead is not extinguished.”

[AD 636] Isidore of Seville on Ruth 4:1-6
When Ruth entered the land of Israel with her mother-in-law, it was provided (on account of the merits of her prayers) that she be married to a man of the lineage of Abraham and whom, indeed, she at first believed to be her closest kinsman. He [the nearest kinsman] said that he could not marry her and, when he had withdrawn, Boaz was married to her, with the witness of ten elders. He [Boaz] who previously confessed himself unable to marry that same woman was united with her and was blessed by those ten elders.It is thought that this passage prefigures John the Baptist who, when he himself was thought by the people of Israel to be Christ and was asked who he was, did not deny who he was but confessed it, saying that he was not Christ. And those who were sent persisted in these inquiries about who he was. He answered, “I am the voice crying in the desert.” He confessed the good news about the Lord, saying, “He who has the bride is the bridegroom.” He showed that he himself was the friend of the groom [the best man], since he added, “Truly, the friend of the groom is he who stands and hears him and rejoices on account of the groom’s voice.” And so they thought he was Christ, because they did not understand that Christ had come on the day of the visitation and that he who was earlier promised by the prophets’ voices was the church’s bridegroom. But just as he told her he was not her kinsman but then afterwards Ruth was united with Boaz, so Christ, who is the true bridegroom of the church, whom the sayings of all the prophets proclaim, was deemed worthy, from all Gentile nations, to claim the church, to present to God the Father unnumbered people throughout the whole orb of the world, because his kinsman took off the sandals.

[AD 397] Ambrose of Milan on Ruth 4:7-12
For, by the law, when a man died, the marriage bond with his wife was passed on to his brother or other male next of kin, in order that the seed of the brother or next of kin might renew the life of the house. And so it was that Ruth, though she was foreign-born, had possessed a husband of the Jewish people who had left a kinsman of near relation. Although she was seen and loved by Boaz while gleaning and maintaining herself and her mother-in-law with what she gleaned, she could not become the wife of Boaz until she had first loosed the shoe from him whose wife she ought, by the law, to have become.The story is a simple one, but deep are its hidden meanings, for that which was done was the outward signs of something more. If indeed we should stretch the sense so as to fit the letter exactly, we should almost find the words an occasion of a certain shame and horror, that we should regard them as intending and conveying the thought of common bodily intercourse. Rather it was the foreshadowing of one who was to arise from the Jewish people—whence Christ was, after the flesh—who should, with the seed of heavenly teaching, revive the seed of his dead kinsman, that is to say, the people, and to whom the precepts of the law, in their spiritual significance, assigned the sandal of marriage, for the espousals of the church.

[AD 407] John Chrysostom on Ruth 4:7-12
Those things which happened to Ruth should be seen as figures. For she was an outsider and had fallen into extreme penury; but Boaz, seeing her, did not despise her on account of her poverty, nor was he horrified on account of her impiety; even as Christ received the church, who was both a stranger and laboring, in need of great good things. Ruth is not joined with her consort before forsaking her parents and her nation and her native land: never was anyone so much ennobled by marriage. Thus the church was not made loveable to her spouse before she had forsaken her prior customs. The prophet says, “Forget your people.”

[AD 458] Theodoret of Cyrus on Ruth 4:7-12
The elders confirmed the marriage with a blessing, saying, “The Lord made this woman,” etc. Moreover, “So that she may be an example of virtue in Ephrathah,” they predicted the salvific birth through which Bethlehem was made famous among all people.

[AD 636] Isidore of Seville on Ruth 4:7-12
It was an old custom that if a groom wished to divorce his bride he took off his sandal and this was the sign of the divorce. Consequently, he was ordered to take off his sandals, lest he approach the church wearing sandals like a bridegroom; for this office was reserved for Christ, who is the true bridegroom. However, the blessing of the ten elders showed that all Gentile peoples were saved and blessed in the name of Christ. For iota signifies ten in Greek, and this first letter will signify the name of the Lord Jesus in full; which shows, as we said, that all peoples are saved through him and are blessed. Therefore, let no one doubt these things that were said, since it may be seen that they were everywhere and from the beginning prefigured by antecedent figures; and they were clearly fulfilled in this way through the advent of the Lord; and which were superfluous, being completed in this way by the accord of all voiced in truth; and by all “figures” of the holy Scriptures, which he who promised [them] fulfilled through his son, Jesus Christ our Lord, king, and redeemer and savior, with whom is honor and glory from age to age. Amen.

[AD 1781] Richard Challoner on Ruth 4:11
Ephrata: Another name of Bethlehem.
[AD 373] Ephrem the Syrian on Ruth 4:13-17
Let Tamar rejoice that her Lord has come, for her name announced the son of her Lord, and her appellation called you to come to her.By you honorable women made themselves contemptible, [you] the One who makes all chaste. She stole you at the crossroads, [you] who prepared the road to the house of the kingdom. Since she stole life, the sword was insufficient to kill her.
Ruth lay down with a man on the threshing floor for your sake. Her love was bold for your sake. She teaches boldness to all penitents. Her ears held in contempt all [other] voices for the sake of your voice.
The fiery coal that crept into the bed of Boaz went up and lay down. She saw the Chief Priest hidden in his loins, the fire for his censer. She ran and became the heifer of Boaz. For you she brought forth the fatted ox.
She went gleaning for love of you; she gathered straw. You repaid her quickly the wage of her humiliation: instead of ears [of wheat], the Root of kings, and instead of straw, the Sheaf of Life that descends from her.

[AD 1107] Theophylact of Ohrid on Ruth 4:13-17
And Boaz begat Obed of Ruth. Ruth was a foreigner, but nevertheless she was married to Boaz. So, too, the church is from among the Gentiles. For like Ruth, these Gentiles had been foreigners and outside the covenants, yet they forsook their people, their idols and their father, the devil. And as Ruth was wed to Boaz of the seed of Abraham, so too was the church taken as bride by the Son of God.
