1 Peter 3:1-6 NIV
Wives, in the same way submit yourselves to your own husbands so that, if any of them do not believe the word, they may be won over without words by the behavior of their wives, when they see the purity and reverence of your lives. Your beauty should not come from outward adornment, such as elaborate hairstyles and the wearing of gold jewelry or fine clothes. Rather, it should be that of your inner self, the unfading beauty of a gentle and quiet spirit, which is of great worth in God’s sight. For this is the way the holy women of the past who put their hope in God used to adorn themselves. They submitted themselves to their own husbands, like Sarah, who obeyed Abraham and called him her lord. You are her daughters if you do what is right and do not give way to fear.
