Jeremiah 11:3-5

and say thou unto them, Thus saith the LORD God of Israel; Cursed be the man that obeyeth not the words of this covenant, which I commanded your fathers in the day that I brought them forth out of the land of Egypt, from the iron furnace, saying, Obey my voice, and do them, according to all which I command you: so shall ye be my people, and I will be your God: that I may perform the oath which I have sworn unto your fathers, to give them a land flowing with milk and honey, as it is this day. Then answered I, and said, So be it, O LORD.
