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, for you are a close relative." 10 Then he said, "Blessed are you of the Lord, my daughter! For you have shown more kindness at the end than at the beginning, in that you did not go after young men, whether poor or rich. 11 And now, my daughter, do not fear. I will do for you all that you request, for all the people of my town know that you are a virtuous woman. 12 Now it is true that I am a close relative; however, there is a relative closer than I. 13 Stay this night, and in the morning it shall be that if he will perform the duty of a close relative for you--good; let him do it. But if he does not want to perform the duty for you, then I will perform the duty for you, as the Lord lives! Lie down until morning."

What in one age or nation would be improper, is not always so in another age or another nation. Being a judge of Israel, Boaz would tell Ruth what she should do; also whether he had the right of redemption, and what methods must be taken, and what rites used, in order to accomplishing her marriage with him or another person. The conduct of Boaz calls for the highest praise. He attempted not to take advantage of Ruth; he did not disdain her as a poor, destitute stranger, nor suspect her of any ill intentions. He spoke honourably of her as a virtuous woman, made her a promise, and as soon as the morning arrived, sent her away with a present to her mother-in-law. Boaz made his promise conditional, for there was a kinsman nearer than he, to whom the right of redemption belonged.
