When Joseph sees his brothers, his wisdom says that he should not reveal who he is. I want to stop and say here that through the narrative so far, God has blessed Joseph with great wisdom. James 1:5 tells us that: "If any of you lack wisdom let him ask of God who giveth to all men liberally and upbraideth not, and it shall be given to him." We don't have to look at Joseph and wish we had that kind of wisdom. it is available to every believer, but we must ask for it.
As we watch the unfolding of God's divine plan for the family of Jacob to travel to Egypt, you will find that Joseph did it one step at a time. Joseph gives the command for them to bring their youngest brother with them the next time they come. This is Benjamin who is Joseph's full brother by birth. He keeps one of them as a prisoner in order that they would follow through with their promise to bring Benjamin with them when they returned. Such wisdom is phenomenal. As I look at this, I can see what kind of person I should be as far as I am concerned. Can God move me as He moved Joseph? I look at Joseph as a man who had a close relationship with God. We all have the ability to have this kind of close relationship, but it will take some effort on our part.
