Deuteronomy 30:10-14

if you obey the LORD your God to keep His commandments and His statutes which are written in this book of the law, if you turn to the LORD your God with all your heart and soul. “For this commandment which I command you today is not too difficult for you, nor is it out of reach. It is not in heaven, that you should say, ‘Who will go up to heaven for us to get it for us and make us hear it, that we may observe it?’ Nor is it beyond the sea, that you should say, ‘Who will cross the sea for us to get it for us and make us hear it, that we may observe it?’ But the word is very near you, in your mouth and in your heart, that you may observe it.
