Images of the Holy One

(27) And God created man in His own image, in the image of God created He him; male and female created He them.

It was for this reason that man was first created as one person [Adam], to teach you that anyone who destroys a life is considered by Scripture to have destroyed an entire world; any any who saves a life is as if he saved an entire world." And also, to promote peace among the creations, that no man would say to his friend, "My ancestors are greater than yours."

(15) Shammai says: Make your Torah permanent, say little and do much, and receive every person with a pleasant countenance.
