The man wants and is allowed to get this close to his wife. He longs to play with her breasts. That is as good as seeing clusters of grapes on the vine. So beautiful to see! He gets so close to her that he smells her breath. It is a scent that he enjoys, like when you smell the scent of an apple when you hold it close to your nose.
9 Je me dis: Je monterai sur le palmier, J'en saisirai les rameaux! Que tes seins soient comme les grappes de la vigne, Le parfum de ton souffle comme celui des pommes,
