You are to follow the Lord your God and fear Him. Keep His commandments and listen to His voice; serve Him and hold fast to Him. Deuteronomy 13:4

But this is what I commanded them, saying, ‘Obey My voice, and I will be your God, and you shall be My people. And walk in all the ways that I have commanded you, that it may be well with you. Jeremiah 7:23
