Elijah's Holomessage

 is a holotape in the Fallout: New Vegas DLC Dead Money. It can be found on the terminal in the Abandoned BoS Bunker after completing the DLC.

If you take the message to Veronica it will trigger unique dialogue. First talk to her about herself ("Tell me about yourself.") and ask about Father Elijah. Ask her where he is now and then ask her about a note. After that, close dialogue and open up dialogue again and a new dialogue option will appear. After talking to Veronica about this, Veronica gets the Elijah's Last Words perk, giving her a 150% increase of attack speed and a 25% chance to knock down enemies. If the Courier instead, chooses to have Veronica open it and but not watch it and return it back to the Courier, he/she will gain the Elijah's Ramblings perk which increases all melee critical hit damage by 150%
