Peer (H6287) denotes a beautiful headdress, turban, or ornament — particularly the priestly turban and the crown of beauty. It comes from paar (to glorify, to beautify) and is connected to the concept of divine adornment and transformation.
The theological weight of peer clusters around the act of exchange and transformation. Isaiah 61:3 is the axis: 'to give them a headdress instead of ashes' — the messianic mission replaces mourning with beauty, ashes with a crown. Jesus declared this fulfilled in himself (Lk 4:18-21). The priest's turban (peer) marked consecration and dignity; the messianic gift extends this priestly beauty to all who mourn. When God adorns His people, He gives them back the dignity sin stripped away. Beauty is not superficial in Scripture — it is the mark of restoration.
