Genesis 27:17

And she gave the savory meat and the bread, which she had prepared, into the hand of her son Jacob. Thus Rebekah had taken the matter of the patriarchal blessing into her own hands. She had in mind, of course, the promise which she had received, but her rashness caused her to identify her plan with the plan of God. She felt that she must come to the aid of the divine dispensation, but her manner of acting had neither God's command nor His promise. It was the mercy of the Lord which afterward turned her human machinations for the best.
