31 Then Joseph said to his brothers and to his father’s household, “I will go up and speak to Pharaoh and will say to him, ‘My brothers and my father’s household, who were living in the land of Canaan, have come to me. 32 The men are shepherds; they tend livestock, and they have brought along their flocks and herds and everything they own.’ 33 When Pharaoh calls you in and asks, ‘What is your occupation?’ 34 you should answer, ‘Your servants have tended livestock from our boyhood on, just as our fathers did.’ Then you will be allowed to settle in the region of Goshen, for all shepherds are detestable to the Egyptians.” Genesis 46:31-34
While Joseph was a powerful man in Egypt, he was still subservient to the Pharoah. He knew how to address him and what to say (and what not to say). Joseph had learned quite a bit as he made his way throughout the palace. It wasn’t as if Pharoah and Joseph were buddy buddies. No, there was still respect between the two, but the Pharoah still was Pharoah.
In fact, Joseph anticipated what the Pharoah would say to his family because it was his job to know the Pharoah likes and dislikes, and to anticipate many of his moves.
Fortunately for us, we have a better “advocate, the Holy Spirit, whom the Father will send in my name, will teach you all things and will remind you of everything I have said to you.” John 14:26
The Holy Spirit knows the pitfalls, dangers, and obstacles we encounter before we encounter them. The more we immerse ourselves in and memorize the Word of God, the more the Holy Spirit can remind us of what we’ve read.
In other words, He can’t remind us of something that isn’t already in our hearts and souls.
