מדרש על מיכה 4:1

… R’ Hoshaya said in the name of R’ Afes – in the future, Jerusalem will be as a torch for the nations of the world and they will go by her light. What is the reason? “And nations shall go by your light…” (Yeshayau 60:3) R’ Acha said – Israel is compared to an olive, “A leafy olive-tree fair with goodly fruit, has the Lord called your name…” (Yirmyahu 11:16) and the Holy One to a lamp, “Man's soul is the Lord's lamp…” (Mishle 20:27) Just as it is the way to put oil in a lamp and they give light together as one, so to the Holy One said to Israel – My children, since My light is your light and your light Mine, you and I will go together and illuminate Zion, “Arise, shine, for your light has come…” (Yeshayahu 60:1)
