1 Peter 3:3-4

Let not yours be the [merely] external adorning with [elaborate] interweaving and knotting of the hair, the wearing of jewelry, or changes of clothes; But let it be the inward adorning and beauty of the hidden person of the heart, with the incorruptible and unfading charm of a gentle and peaceful spirit, which [is not anxious or wrought up, but] is very precious in the sight of God.
