Deuteronomy 30:10-13

if you listen to and obey the voice of the LORD your God to keep His commandments and His statutes which are written in this Book of the Law, and if you turn to the LORD your God with all your heart and with all your soul (your entire being). “For this commandment which I am commanding you today is not too difficult for you, nor is it out of reach. It is not [a secret hidden] in heaven, that you should say, ‘Who will go up to heaven for us and bring it to us, so that we may hear it and obey it?’ Nor is it beyond the sea, that you should say, ‘Who will cross the sea for us and bring it to us, so that we may hear it and obey it?’
