Deuteronomy 11:26-28

‘See, I am setting before you to-day a blessing and a reviling: the blessing, when ye hearken unto the commands of Jehovah your God, which I am commanding you to-day; and the reviling, if ye do not hearken unto the commands of Jehovah your God, and have turned aside out of the way which I am commanding you to-day, to go after other gods which ye have not known.
