SERAPHIM 'burning ones or nobles".This type of heavenly beings have 6 wings but they only use 2 of them for flying.The other wings are use to cover their face and feet because being so close to God,they would witness His full glory which would be too powerful to behold.Their primary duty is to constantly glorify and praise God and they may also be personal "attendant" angels of God.
