Deuteronomy 11:26-28

Webster(i) 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 from the way which I command you this day, to go after other gods which ye have not known.
