We provide pleasant milk for you to drink within the delicate system of their veins and arteries. 66 And from the fruit of the date-palm and the vine, ye get out wholesome drink and food: behold, in this also is a sign for those who are wise. 67 And your Lord inspired the bee that, “Build homes in hills, and in trees, and in rooftops.” 68 “Then eat from all kinds of fruits, and tread the ways of your Lord which are soft and easy for you”; from their bellies comes a drink of various colours, in which is health for mankind; indeed in this is a sign for people who ponder. 69 God created you; then He shall cause you to die: and some shall have their lives prolonged to abject old age, ceasing to know anything after once having had knowledge. God is all knowing and powerful. 70
