14:18-20
`` Ah , '' said the astrologer , `` Melchisedek is one of the most mysterious of all the figures in the Holy Bible . He was king of Salem , sacrificer to the Most High God . He blessed Abraham and Abraham gave him tithes of the spoil of the vanquished kings of Sodom and Gomorrah . That is the story in Genesis 14:18-20 . But Saint Paul cites him also , in Hebrews 7 , and in the third verse of that chapter says that Melchisedek , ` without father , without mother , without descent , having neither beginning of day , nor end of life , but made like unto the Son of God , abideth , a priest continually . ' In Hebrews 5:6 Paul , quoting Psalm 110:4 , says Jesus is called ` a priest forever after the order of Melchisedek . ' `` All this , you see , is obscure enough .
