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.
Numbers 6: 24-26
or as Mr. Spock would say:
Live long and prosper!
(*editor's note: the top picture shows the traditional position for the hands of the high priest as he blessed the congregation. Leonard Nemoy, himself Jewish, used this as the basis for the famous Vulcan salute. Neat, eh?)
