Deuteronomy 27-28
"Moses and the priests, who are Levites, said to all Israel, "Be silent, O Israel, and listen! You have now become the people of the LORD your God. Obey the LORD your God and follow his commands and decrees that I give you ..."
"If you fully obey the LORD your God and carefully follow all his commands I give you, the LORD your God will set you high above all the nations on earth... blessings will come upon you and accompany you if you obey the LORD your God... However, if you do not obey the LORD your God and do not carefully follow all His commands and decrees, ... curses will come upon you and overtake you...If you do not carefully follow all the words of the law, ... and do not revere this glorious and awesome name—the LORD your God- the LORD will send fearful plagues on you and your descendants, harsh and prolonged disasters, and severe and lingering illnesses... Then the LORD will scatter you among all nations, from one end of the earth to the other. Among those nations you will find no repose, no resting place for the sole of your foot. There the LORD will give you an anxious mind, eyes weary with longing, and a despairing heart. You will live in constant suspense, filled with dread both night and day, never sure of your life. "
