Deuteronomy 11:26-28

“Behold, today I am setting before you a blessing and a curse— the blessing, if you listen to and obey the commandments of the LORD your God, which I am commanding you today; and the curse, if you do not listen to and obey the commandments of the LORD your God, but turn aside from the way which I am commanding you today, by following (acknowledging, worshiping) other gods which you have not known.
