bellies
in Edition Clear Qur'an by Talal Itani / An-Nahl (The Bee)

16:66And there is a lesson for you in cattle: We give you a drink from their bellies, from between waste and blood, pure milk, refreshing to the drinkers.

16:69Then eat of all the fruits, and go along the pathways of your Lord, with precision. From their bellies emerges a fluid of diverse colors, containing healing for the people. Surely in this is a sign for people who reflect.
