As many verses are in the Bible, it a mystery. Melchizedek, without father or mother was a high priest of God,,a priest to whom even the great Abraham gave a tithe..wow! Only God knows his lineage.And I am continually in awe...
In Genesis -1- we have God, in Genesis -2- we have The Lord God and in Genesis -3- we have the serpent driving a wedge between the Lord and that of God, for he does not speak of the fact that it by commandment of The Lord God that he challanges but speaks of (did God say ?). What these kings are trying to do( by way of SERPENT )is offer the position of high priest to Abram of only GOD but Abram stands correctly and by no evil when he presents that he is of The Lord the most high God. Thus he will be presented with" Abraham".
