Deuteronomy30:11-14

Now what I am commanding you today is not too difficult for you or beyond your reach. It is not up in heaven, so that you have to ask, "Who will ascend into heaven to get it and proclaim it to us so we may obey it?" …No, the word is very near you; it is in your mouth and in your heart so you may obey it.
(Deuteronomy申命記30:11-14)
