1 Peter 3:3-6

Wives, your beauty should not only be on the outside: how you fix your hair, your jewelry, and what you wear. But rather, you should be known for the beauty in your heart, the incorruptible adornment of a gentle and quiet spirit, which is precious to GOD. For in the same way, the holy women of the past, who put their hope in GOD, adorned themselves in like manner, and were submissive to their husbands. For example: Sarah, who obeyed her husband, Abraham, and called him her master. You are her daughters when you do what is right and do not give way to fear.
