Deuteronomy 30:12-14
12 It is not in heaven, that you should say, ‘aWho will go up to heaven for us and get it for us and make us hear it, that we may do it?’ 13 Nor is it beyond the sea, that you should say, ‘Who will cross the sea for us and get it for us and make us hear it, that we may do it?’ 14 But the word is very near you, in your mouth and in your heart, that you may do it.
