I suppose we can view Genesis 14 as a story about Abraham/Abram as political leader who has to deal with rival leaders and neighboring leaders.
As the story progresses, Abraham/Abram can be seen as one of the victors alongside the king of Sodom who is a pseudo-ally victor.
The following scripture passages corresponds to events that relate to worldly aspects:
Genesis 14:1-17 -->war between Kings, and Abraham's involvement
Gensis 14:21-24 -->Abraham's interaction with king of Sodom who is a
However, Genesis 14:18-20 is a sub-narrative that symbolizes Godly and Divine aspects of the Genesis 14 story.

"In Genesis chapter 14, Melchizedek appears and then disappears so suddenly that Hebrews chapter 7, describes him as
( Hebrews 7:3 )
Without father, without mother, without genealogy,
having neither beginning of days nor end of life, but made like the
Son of God, he remains a priest perpetually.
and as a type for Jesus. "
The significance of the insertion/interleaving/interlinearing of the King Melchizedek's sub-narrative into the Genesis 14's historical-political story shows us how God interacts with Abraham as he faces challenges & major milestones in this world.
I suppose we as Christians could view Genesis 14 as a very broad & general pattern of how we Christians have to interact with God, and this world ( i.e., we are In this world, but Not of the world. )
19 If you were of the world, the world would love its own; but because
you are Not of the world , but I chose you out of the world, because of this the world hates you.
14 I have given them Your word; and the world has hated them, because
they are Not of the world, even as I am Not of the world. 15 I do not ask You to take them out of the world, but to keep them [a]from
[b]the evil one. 16 They are not of the world, even as I am not of
the world. **
Abraham serves as a role model to us Christians because Abraham's actions/reactions show that he is Not of this world when he gives a 1/10 of his materialistic gain from his victory in said war of Caanan in Genesis 14:18-20
He gave him a tenth of all.
Abraham gave 10% of material gain to God( sort of represented by Abraham's interaction with King Melchizedek who Represents God )
Furthermore, Abraham gives credit to God by rejecting the materialistic world( i.e. represented by king of Sodom) which is described in Genesis 14:21-24 bible passage, and appropriately giving credit to God
21 The king of Sodom said to Abram, “Give the [e]people to me and take
the goods for yourself.” 22 Abram said to the king of Sodom, “I have
[f]sworn to the Lord [g]God Most High, [h]possessor of heaven and
earth, 23 that I will not take a thread or a sandal thong or anything
that is yours, for fear you would say, ‘I have made Abram rich.’ 24
[i]I will take nothing except what the young men have eaten, and the
share of the men who went with me, Aner, Eshcol, and Mamre; let them
take their share.”
