Parashat Miketz begins with a description of Pharaoh's dreams, which Yosef will ultimately interpret as heralding the onset of seven years of surplus, which will be followed by seven years of drought. Pharaoh dreams of seven lean, emaciated cows devouring seven sturdy, healthy cows, as well as seven withered sheaves of grain "eating" seven robust sheaves. This vision, Yosef explains to the king, symbolizes the "lean" years of famine that will overtake and "devour" the seven years of surplus.
