Shalom Aleichem

A faithful Friend helped me understand this invaluable "Blessing." This is what he wrote ...
"Shalom Aleichem"

It is the Hebrew salutation that says "hello" or "goodbye" , but literally is "Peace to upon you!" and the appropriate response is "Aleichem Shalom!" which reads "And upon you, peace!" Shalom is also that "wide word" which is the OT equivalent of "Health", "Salvation", "Well being", etc.
I use it as the short version of the benediction in Numbers 6:24-26
The Lord bless you and keep you;
the Lord make his face to shine upon you, and be gracious to you;
the Lord lift up his countenance upon you,
and give you peace.
So they shall put my name on the Israelites, and I will bless them.

Shalom be upon us all
