Ruth’s Redemption Assured
1 Then Naomi her mother-in-law said to her, “My daughter, shall I not seek security (Lit. rest) for you, that it may be well with you?
2 Now Boaz, whose young women you were with, is he not our relative? In fact, he is winnowing barley tonight at the threshing floor.
3 Therefore wash yourself and anoint yourself, put on your best garment and go down to the threshing floor; but do not make yourself known to the man until he has finished eating and drinking.
4 Then it shall be, when he lies down, that you shall notice the place where he lies; and you shall go in, uncover his feet, and lie down; and he will tell you what you should do.”
5 And she said to her, “All that you say to me I will do.”
6 So she went down to the threshing floor and did according to all that her mother-in-law instructed her.
7 And after Boaz had eaten and drunk, and his heart was cheerful, he went to lie down at the end of the heap of grain; and she came softly, uncovered his feet, and lay down.
8 Now it happened at midnight that the man was startled, and turned himself; and there, a woman was lying at his feet.
9 And he said, “Who are you?”
So she answered, “I am Ruth, your maidservant. Take your maidservant under your wing (Or Spread the corner of your garment over your maidservant), for you are a close relative (A kinsman-redeemer, Heb. Goel).”
Law and custom gave Ruth, who was now proselyted to the true religion, a legal claim upon Boaz. It was customary for widows to assert this claim, De 25:5-10. But this is not recorded for imitation in other times, and is not to be judged by modern rules. And if there had been any evil in it, Ruth was a woman of too much virtue and too much sense to have listened to it. Matthew Henry’s Concise Commentary
