The Lord's special preparation for the tabernacle was compounded from principal spices in fixed measure, namely pure myrrh with sweet cinnamon and sweet calamus. That compound was set apart as sacred and was not to be put to common use. Its composition was not to be copied, nor was it to be placed upon unauthorized persons.
