Why have people changed?

Leban, Jacob’s mother’s brother, knew that the Lord had blessed him on Jacob’s account (Gen. 30:27).

Jacob also knew that Leban had little before he came and it had increased to a multitude (v. 30).

And Jacob knew that the Lord had blessed Leban wherever he turned (v. 30).

However, when Jacob was at Leban’s house for 20 years (31:41),

He noticed that Leban’s attitude toward him wasn’t what it had been (v. 2).

And he heard that Leban’s sons were saying, “Jacob has taken everything our father owned and has gained all this wealth from what belonged to our father” (v. 1).

Why did Leban and his sons changed?  Why couldn’t Leban treat Jacob as before?

Even though Leban knew that God had blessed him through Jacob, why didn’t he treat Jacob as before?

Why did Leban’s sons think that Jacob had taken everything from their father owned

and had gained all his wealth from what belonged to their father

instead of thinking that God had blessed their father through Jacob?

Was it because Jacob “grew exceedingly prosperous and came to own large flocks,

and maidservants and menservants, and camels and donkeys”? (30:43)

I think God used all these things in order to make Jacob to go back

to the land of his fathers and to his relatives (31:3; cf. v.13).
