How did Rebekah use a young goat to deceive Isaac?
Rebekah took the skins of the kid of the goats and put them on Jacob's hands and the smooth of his neck, then prepared savory meat and bread and placed them in Jacob's hand. This disguise and meal were intended to make Jacob seem and feel like Esau, deceiving Isaac.
Les explains that Rebekah used the kid of the goats to deceive by putting its skins on Jacob's hands and the smooth of his neck. She also gave the savory meat and bread she had prepared into Jacob's hand. Jacob then came to Isaac and said, "I am Esau thy firstborn." Les notes that while it looks like a bold-faced lie, Jacob was actually in the role God Himself had designated for the firstborn. By God's reckoning, Jacob was not lying; he was in the position God intended. This illustrates the principle that what you sow, you reap, and what goes around comes around.
