Deuteronomy 30:11-14
11“For this commandment which I am commanding you today is not too difficult for you, nor is it far from you. 12“It is not in heaven, 1that 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, 1that 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.
