6 And Joseph was the governor over the land, and he it was that sold to all the people of the land: and Joseph’s brethren came, and bowed down themselves before him with their faces to the earth.
I imagine that Joseph needed to set up some sort of delegation, distributing the work of storing and selling the grain to a whole army of workers. But evidently he didn’t delegate his way out of the process entirely. He was still integral to the operation, apparently being responsible for negotiating the sales with foreign customers.
And here, at last, we find the fulfillment of Joseph’s prophecy from many years ago. We know he was seventeen when he had his dreams, thirty when he was taken out of prison by Pharaoh, that seven years of bounty had already passed, and some amount of time in famine before Jacob’s sons came to buy grain. Thus, over twenty years had passed since Joseph first related his dreams to his brothers, which showed that they would come and bow to him.
Which goes to show that the Lord’s timing is on a far different timescale from our own. There is no sense of “too long” since the promise was given, no expiration, no distance of time or status that render His word invalid. The sequence of events that had transpired to bring this prophecy to pass were impossible to anticipate, there was no “lucky guessing” on Joseph’s part to prophesy of it. This development could only have been foretold by an omniscient being who had already seen all that would be.
