Song of Solomon 4:10 (ESV)

10 How beautiful is your love, my sister, my bride! How much better is your love than wine, and the fragrance of your oils than any spice!

How wonderful and stimulating then is the love of your wife who is also your sister in the Lord. Then her love for you is better than wine and sweeter than the most delightful fragrances. Such love is never a threat but truly brings peace and joy.
