From the Babylonian Talmud, Book 3:

“The rabbis taught: Six things are said with regard to demons, three in which they are like the angels: they have wings, they float from one end of the world to the other, and they know what is about to be; and three in which they are like men: they eat and drink, they are fruitful and multiply, and they are mortal.

Six things are said with regard to men, three in which they are like angels: they have knowledge like the angels, they go with stature erect, and they speak in the holy language; and three like the beasts: they eat and drink like beasts, and they are fruitful and multiply, and they relieve nature.”
