For if] In this and the next verse there are reasons given why Christ could not be a Priest upon earth. First, because the earthly Priests were ordained by the Law to offer onely earthly and carnall sacrifices; but there were no such sacrifices required of the Priest according to the order of Melchisedec, Psalms 40:6. Vers. 4. Secondly, the Legall Priesthood and the sacrifices administred by it, were shadows of heavenly things, viz. of the Priesthood of Christ and his sacrifice: whence it evidently followes, that his Priesthood was to be a heavenly Priesthood, and his sacrifice to be a heavenly sacrifice, vers. 5. there are priests] Or, they are priests.
