It is written in Midrash Tanchuma, “And Jacob saw that there was grain,” as the writing says, “Happy is he who asks Jacob for help.” Why was it not said, “who asks Abraham,” or “asks Isaac,” but rather “asks Jacob”? It teaches that the Creator did not stand over Abraham, or over Isaac, but over Jacob, as it is written, “And the Lord stood over him.”
Rabbi Simon said, “The King does not stand on his field when it is sown, or when it is ploughed, or when it is being hoed. When does He stand over it? When it is ripe. Thus, Abraham hoed, as was said, ‘Arise, walk through the land’; Isaac sowed, and was said, ‘And Isaac sowed.’ He did not stand on it until Jacob came, when there was ripening of the crop, as was said, ‘Israel are dedicated to the Lord, His first crop.’ The Creator stood over him, as was said, ‘And the Lord stood over him.’ Thus, ‘Happy is he who asks Jacob for help.’”
We should ask, 1) Why is specifically Jacob called “crop”? 2) What is the connection between the allegory and the lesson, that because of it we should say that the Creator stood specifically over Jacob and not over Abraham or Isaac? 3) What does it mean that the Creator stood over him? After all, Abraham and Isaac were also rewarded with the Creator speaking with them, as it is written about Abraham several times, “And the Lord said to Abraham… and He said to him, ‘I am the Lord, who took you out of the land of the Chaldeans.’” Also, the Creator spoke with Isaac several times, “And the Lord appeared to him and said, ‘Do not go down to Egypt.’”
Also, what is the importance that was said about Jacob during the dream, as it is written, “And he dreamed… and the Lord stood over him”?
