Did Joseph tell Jacob about his brothers’ deed of having sold him for a price to the Ishmaelites after him having become the minister in Egypt? I think so. He reported all matters to his father and to destroy his brothers’ credibility he’d have done that further he couldn’t have concocted a better story than telling the truth as to how he ended up in Egypt. Truth stated to his advantage! Or had he learnt the lesson, not to carry old and damaging tales to others, with all those terrible experiences? Maybe. But he in all probability to wangle the birthright he might have stated the fact. But what was the fact? He wrote the history in Egypt! God gives the good man the opportunity to give final touches to history.
