'Cheated' in the Bible

So he said, “Isn’t he rightly named Jacob? For he has cheated me twice now. He took my birthright, and look, now he has taken my blessing.” Then he asked, “Haven’t you saved a blessing for me?”

and that he has cheated me and changed my wages 10 times. But God has not let him harm me.

Therefore, to have legal disputes against one another is already a moral failure for you. Why not rather put up with injustice? Why not rather be cheated?
