This dream is described in Genesis 41:1-7. In Pharaoh's dream, he saw seven fat and sleek cows emerging from the Nile River, followed by seven gaunt and thin cows. The thin cows then proceeded to devour or eat up the seven fat cows. This dream was interpreted by Joseph, who was known for interpreting dreams. He interpreted this particular dream as a prediction of seven years of abundance in Egypt followed by seven years of famine.
