Shalom aleichem – Peace be upon you (שָׁלוֹם עֲלֵיכֶם) The correct response to this greeting is "Aleichem shalom" (Upon you be peace). Interestingly, it's in the plural, so it can also be used in the context of a group of people. It also includes every part of one's humanity: body, spirit and soul. Shalom itself means "completeness" or "wholeness", so what we're actually saying is "may you have completeness in every aspect of your humanity." Note, this same "Shalom aleichem" dynamic can be seen in Luke 10:5 when Jesus sends out the 72 disciples in pairs, and the exact words are used when the resurrected Jesus "came and stood among them and said, "Shalom aleichem!" (John 20:26). The word Jerusalem in Hebrew is Yerushalayim which is made up of two Hebrew words; yeru which means "you will see" and shalom which means "the peace of God". So Jerusalem is supposed to be the place where you will see the peace of God.
