Sh'mot (Exo) 33:16-17

For how else is it to be known that I have found favor in your sight, I and your people, other than by your going with us? That is what distinguishes us, me and your people, from all the other peoples on earth.” (iv) ADONAI said to Moshe, “I will also do what you have asked me to do, because you have found favor in my sight, and I know you by name.”
