Jeremiah 11:4, 7

that I commanded your fathers when I brought them out of the land of Egypt, from the iron furnace, saying, Listen to my voice, and do all that I command you. So shall you be my people, and I will be your God

For I solemnly warned your fathers when I brought them up out of the land of Egypt, warning them persistently, even to this day, saying, Obey my voice.
