The man so longs for his wife. Thus, he even asks if she wants to turn her eyes away from him. Her love so overwhelms him that it confuses him. He feels how overwhelmingly great a gift he has received from God in her.
She stands out like a flock of goats with white fur that stands out when they are leaping in the green pastures.
5 Turn away your eyes from me, for they overwhelm me Your hair is like a flock of goats leaping down the slopes of Gilead.
