Which epic characteristic is used in this excerpt from the Iliad by Homer?

Then thus the king: “Shall I my prize resign
With tame content, and thou possess'd of thine?
Great as thou art, and like a god in fight,
Think not to rob me of a soldier's right.
At thy demand shall I restore the maid?
First let the just equivalent be paid;
Such as a king might ask; and let it be
A treasure worthy her, and worthy me.
