17 If the whole body were an eye, where would the hearing be? If the whole body were an ear, where would the sense of smell be? 18 But as it is, God has arranged each one of the parts in the body just as he wanted.n 19 And if they were all the same part, where would the body be? 20 As it is, there are many parts, but one body. 21 The eye cannot say to the hand, “I don’t need you!” Or again, the head can’t say to the feet, “I don’t need you!”
