Deuteronomy 11:26-28

Leeser(i) 26 Behold, I lay before you this day a blessing and a curse: 27 The blessing, if ye will hearken unto the commandments of the Lord your God, which I command you this day; 28 And the curse, if ye will not hearken unto the commandments of the Lord your God, and ye turn aside out of the way which I command you this day, to go after other gods, which ye know not.
