The brothers foist a clever deception on Jacob. They soak Joseph's designer coat in animal blood and let Jacob believe a wild animal killed his little pet. Deception brings Jacob to the end of his rope. Jacob's life was marked by generational sin of deception. His grandfather Abraham passed it down to Isaac, who passed it to Jacob who in turn gave it to his sons.
Generational sin appears to be amplified in succeeding generations.
Jacob's competitive deceptive spirit comes home to rest. His compound was a pandora's box of ugly things just waiting to happen. The bottom falls out of Jacob's life. He lost the two relationships that mattered most to him. His favourite wife and his favourite son.
