This is a piece I used to sing a lot when I was young. The words are likely inspired by Psalm 45:8, in which Christ is pictured "coming out of the ivory palaces of heaven to redeem the world, clothed in garments that are perfumed with myrrh for beauty, with aloes for bitterness, and with cassia for healing, the fragrance of which remains to tell of His near presence". The arranger of this version is a bit of a mystery. It only shows his first name and there does not seem to be much out there on the internet. This is a great arrangement though. I hope you enjoy it.
