Ruth 3:4

4But when he goes to sleep, observe the place where he sleeps. And you will approach and lift up the covering, the part which covers near his feet, and lay yourself down, and sleep there; but he will tell you what you are obliged to do.”
3:4Naomi’s plan is not to approach Boaz openly to see if he would take Ruth as his wife, for Ruth was a foreigner. Also, Naomi had been away for many years so that she did not have a secure place in the social structure of the town. She and Ruth were treated somewhat as outsiders. And the women said, “This is that Naomi.” On the other hand, Naomi is not suggesting that Ruth approach Boaz for sexual relations. Rather, she suggests that Ruth approach Boaz when they can be alone, to see if he is interested in her and to let her know that she is interested in him. Naomi’s plan is somewhat inappropriate, yet God uses her flawed plan within His perfect Plan.(Conte)
