Leviticus 25:18-22

“ ‘Follow my decrees and be careful to obey my laws, and you will live safely in the land. Then the land will yield its fruit, and you will eat your fill and live there in safety. You may ask, “What will we eat in the seventh year if we do not plant or harvest our crops?” I will send you such a blessing in the sixth year that the land will yield enough for three years. While you plant during the eighth year, you will eat from the old crop and will continue to eat from it until the harvest of the ninth year comes in.
