Deuteronomy 11:26-28 King James Version (KJV)
26 Behold, I set before you this day a blessing and a curse;
27 A blessing, if ye obey the commandments of the Lord your God, which I command you this day:
28 And a curse, if ye will not obey the commandments of the Lord your God, but turn aside out of the way which I command you this day, to go after other gods, which ye have not known.
Deuteronomy 11:26-28 New International Version (NIV)
26 See, I am setting before you today a blessing and a curse— 27 the blessing if you obey the commands of the Lord your God that I am giving you today; 28 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.
