Deuteronomy 30:12-14

12It is not in the heavens, that you should say, ‘Who will go up for us to the heavens and get it for us, and have us hear it so we may do it?’

13Nor is it across the sea, that you should say, ‘Who will cross over for us to the other side of the sea and get it for us, and have us hear it so we may do it?’

14No, the word is very near to you—in your mouth and in your heart, to do it.
