Genesis 14:18 - Joseph Benson’s Commentary on the Old and New Testaments

It has been a great question among expositors, who Melchizedek was. The Jewish rabbins say that he was Shem, the son of Noah, who was king and priest to those that were descended from him, according to the patriarchal model. And it must be allowed to be probable that Shem was alive at this time, and that he was a great prince. But as Shem's genealogy and birth are recorded in Scripture, and were well known, it could, with no propriety, be said of him, as the apostle says of Melchizedek, that he was “without father (namely, mentioned in the sacred history) and without mother, without beginning of days or end of life:” nor is it at all probable that Moses should introduce Shem under the name of Melchizedek, without any apparent reason, or any the least intimation of his meaning. Many Christian writers have thought that this was an appearance of the Son of God himself, our Lord Jesus, known to Abram at this time by the name of Melchizedek. But this is not consistent with what the same apostle affirms in the same place, Hebrews 7:3, who says, not that he was the Son of God, but that he was “made like him,” αφωμοιωμενος, that is, was made a type of him; nor is it consistent with his affirming that Christ was constituted “a priest after the order of Melchizedek.” Besides, it is said that Melchizedek was “king of Salem:” but we are sure Christ never reigned over any particular city as a temporal prince. It seems sufficiently evident that he was a mere man; but from whom he was descended, or who were his immediate parents or successors, God has not seen fit to inform us: nay, it is probable that God designedly concealed these things from us, that he might be the more perfect type of his eternal Son. He brought forth bread and wine For the refreshment of Abram and his soldiers, and in congratulation of their victory. This he did as king. “As priest of the most high God he blessed Abram,” which, no doubt, was a greater refreshment to Abram's soul than the bread and wine were to his body.
