"For the Lord sees not as man sees: man looks on the outward appearance, but the Lord looks on the heart" is a quote from 1 Samuel 16:7. This Bible passage could be interpreted to mean that God does not oppose outward adornments such as nose piercings.
This passage from The Bible, the holy Christian text, reveals that God does not judge his people based on appearances, but rather on their characters. Other quotes regarding nose piercings that appear in The Bible, as collected by OpenBible.info, include: "Then I asked her, ‘Whose daughter are you?’ She said, ‘The daughter of Bethuel, Nahor's son, whom Milcah bore to him.’ So I put the ring on her nose and the bracelets on her arms," which is from Genesis 24:47.
Another is "And I put a ring on your nose and earrings in your ears and a beautiful crown on your head," from Ezekiel 16:12. These passages specifically point to nose piercings in a seemingly positive light.
