LLAP gesture is made to look like a Shin, the first letter of God & Peace
The famous Vulcan salute—the split-fingered hand sign paired with “Live long and prosper”—was created by actor Leonard Nimoy for the Star Trek: The Original Series episode “Amok Time,” which aired on September 15, 1967
The Jewish Priestly Blessing (Birkat Kohanim)
Nimoy, who was Jewish, adapted the gesture from a childhood memory in a Boston synagogue: [1, 2]
The Ritual: During Orthodox Jewish services, the Kohanim (descendants of the Jewish priestly lineage) extend both of their hands toward the congregation to deliver the Priestly Blessing. [1, 2]
The Letter Shin (ש): By splitting the fingers between the middle and ring fingers and separating the thumb, the hands form the shape of the Hebrew letter Shin, which is the first letter in Shaddai (a Hebrew name for the Almighty). [1, 2]
The Adaptation: Nimoy adapted the two-handed blessing into a single-handed greeting for Spock to give Vulcans a distinct, non-physical way to say hello. [1, 2]
“Live Long and Prosper”
The Phrase: While Nimoy invented the hand gesture, the famous accompanying line—”Live long and prosper”—was written for the script by sci-fi author Theodore Sturgeon.
The Response: The traditional Vulcan reply is “Peace and long life” (often abbreviated as LLAP). [1, 2]

The Spiritual Meaning: In Judaism, the letter Shin represents Shaddai (Almighty God), as well as Shalom (Peace) and Shekhinah (the divine feminine presence of God). [1, 2]
