When God began to create heaven and earth—the earth being uniformed and void, with darkness over the surface of the deep and a wind from God sweeping over the water—God said, “Let there be light.”
Genesis 1:1-3

See, this day, I set before you blessing and curse: blessing, if you obey the commandments of the Lord your God that I enjoin upon you this day; and curse, if you do not obey the commandments of the Lord your God, but turn away from the path that I enjoin upon you this day and follow other gods, whom you have not experienced.
Deuteronomy 12:26-28

See, I set before you this day life and prosperity, death and adversity. For I command you this day, to love the Lord your God, to walk in His ways, and to keep His commandments, His laws, and His rules, that you may thrive and increase, and that the Lord your God may bless you in the land that you are about to enter and possess.
Deuteronomy 30:15-17
