Melchizedek / Melchisedec
The mysterious Melchizedek brought forth the Bread and the Wine, and received tithes, in those days long before the Levitical priesthood and of course they had no way of recognizing him as a precept or 'type' of the Lord Jesus. Did they wonder what message he gave his constituents? And did the Children of Israel consider his position as both a king and a priest when the Levitical priesthood only allowed for one or the other, but not both?
"Without father, without mother..." (Heb7:3), and neither can his generations be determined in the O.T. -- did this Melchizedek simply materialize out of thin air? Is this one of the Christophanies or Theophanies such as the 4th man in the fiery furnace, the man who wrestled Jacob, or the swordsman who appeared to Joshua (5:13).
Melchizedek made what we'd call a cameo appearance in Genesis 14 and then a thousand years went by before he's mentioned again, by David, in Psalms 110:4. Then, ANOTHER thousand years passes before the subject of Melchisedec comes along in the Book of Hebrews.
Dux allows: "It is the glory of God to conceal a thing: but the honour of kings is to search out the matter". Pr25:2
