For this mitzvah which I command you this day, it is not hidden from you, neither is it far off. It is not in heaven, that you should say, "Who shall go up for us to heaven, and bring it to us, that we may hear it, and do it?" Nor is it beyond the sea, that you should say, "Who shall cross the sea for us, and bring it to us, that we may hear it, and do it?" For the thing is very near to you, in your mouth, and in your heart, that you may do it.
Deuteronomy 30:11-14
