1 Peter 3:1-6 (ESV)
1 Likewise, wives, be subject to your own husbands, so that even if some do not obey the word, they may be won without a word by the conduct of their wives, 2 when they see your respectful and pure conduct. 3 Do not let your adorning be external—the braiding of hair and the putting on of gold jewelry, or the clothing you wear— 4 but let your adorning be the hidden person of the heart with the imperishable beauty of a gentle and quiet spirit, which in God’s sight is very precious. 5 For this is how the holy women who hoped in God used to adorn themselves, by submitting to their own husbands, 6 as Sarah obeyed Abraham, calling him lord. And you are her children, if you do good and do not fear anything that is frightening.
