The Traveler’s Prayer – Tefilat HaDerech – is recited at the beginning of a journey, according to the Talmud. In the prayer, the traveler asks for a safe trip.
Here is a translitered version of the Traveler’s Prayer (from The Transliterated Siddur):
Ye-hi ra-tson mi-l’fa-ne-cha,
A-do-nai e-lo-hei-nu vei-lo-hei a-vo-tei-nu,
v’ta-gi-ei-nu lim-choz chef-tsei-nu,
l’cha-yim ul-sim-chah ul-sha-lom.
V’ta-tsi-lei-nu mi-kaf kawl o-yeiv,
v’o-reiv v’lis-tim v’cha-yot ra-ot ba-de-rech,
u-mi-kawl mi-nei fur -a-ni-yot,
ha-mit-ra-g’shot la-vo la-o-lam.
V’tish-lach b’ra-chah b’chawl ma-a-sei ya-dei-nu,
v’ti-t’nei-nu l’chein ul-che-sed ul-ra-cha-mim b’ei-ne-cha,
uv-ei-nei chawl ro-ei-nu.
V’tish-ma kol ta-cha-nu-nei-nu,
ki Eil sho-mei-a t’fi-lah v’ta-cha-nun a-tah.
Ba-ruch a-tah A-do-nai, sho-mei-a t’fi-lah.
Here is a translation (from Twelve Jewish Steps to Recovery):
“May it be Your will, Eternal, My God and God of my ancestors, to lead me, to direct my steps, and to support me in peace. Lead me in life, tranquil and serene, until I arrive at where I am going. Deliver me from every enemy, ambush and hurt that I might encounter on the way, and from all afflictions that visit and trouble the world. Bless the work of my hands. Let me receive divine grace and those loving acts of kindness and mercy in Your eyes and in the eyes of all those I encounter. Listen to the voice of my appeal, for you are a God who responds to prayerful supplication. Praised are you, Eternal, who responds to prayer.”
