Deuteronomy 11:26-29

See, I am setting before you today a blessing and a curse— the blessing if you obey the commands of the LORD your God that I am giving you today; the curse if you disobey the commands of the LORD your God and turn from the way that I command you today by following other gods, which you have not known. When the LORD your God has brought you into the land you are entering to possess, you are to proclaim on Mount Gerizim the blessings, and on Mount Ebal the curses.
