The positioning of the kohen's hands during the Priestly Blessing was Leonard Nimoy's inspiration for Mr. Spock's Vulcan salute in the original Star Trek television series. Nimoy, raised an Orthodox Jew (but not a kohen), used the salute when saying "Live long and prosper." The Priestly Blessing was used by Leonard Cohen in his farewell blessing during "Whither Thou Goest", the closing song on his concerts. Leonard Cohen himself was from a kohen family. He also used the drawing of the Priestly Blessing as one of his logos. See also Footnotes Bibliography Isaac Klein A Guide to Jewish Religious Practice, p. 387–388.
