Ruth 3 carries obvious sexual undertones.
7 After Boaz had finished eating and drinking and was in good spirits, he went to lie down at the end of the heap of grain. Then Ruth went in secretly, uncovered his feet, and lay down.
8 At midnight, Boaz was startled, turned over, and there lying at his feet was a woman!
9 “Who are you?” he asked.
“I am your servant Ruth,” she replied. “Spread the corner of your garment over me, for you are a kinsman-redeemer.”
10 Then Boaz said, “May the LORD bless you, my daughter. You have shown more kindness now than before, because you have not run after the younger men, whether rich or poor. 11 And now do not be afraid, my daughter. I will do for yo u whatever you request since all my fellow townspeople know that you are a woman of noble character. 12 Yes, it is true that I am a kinsman-redeemer, but there is a redeemer nearer than I. 13 Stay here tonight, and in the morning, if he wants to redeem you, good. Let him redeem you. But if he does not want to redeem you, as surely as the LORD lives, I will. Now lie here until morning.”
14 So she lay down at his feet until morning, but she got up before anyone else could recognize her.
Why does Boaz keep calling Ruth "my daughter" as if he is going to marry this woman? Does not that sound incestuous?
