The name Tehinnah in Hebrew letters is תחנה. Below: how its number adds up, which page of the Torah it falls on and what verse stands there. Everything is computed, nothing is guessed.
תחנה
In short
Your name in Hebrew letters is תחנה. A Tanakh name: an Israelite (first in 1 Chronicles 4:12; 1 mention in the Tanakh). Adding up the numbers of its letters gives 463. That number points to Torah page 109 of 354 — in the portion Bo. What that portion is about: Locusts, darkness and the death of the firstborn; the Passover lamb; the exodus from Egypt; the commandment of tefillin. The verse that begins with the first letter of your name and ends with the last is Joshua 21:42. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Tehinnah” — this exact spelling is what was calculated: תחנה. A name from the Tanakh — its Tanakh spelling is used. If your name is spelled differently, correct the Hebrew spelling and the report is recomputed.
they saw not one another, neither rose any from his place for three days; but all the children of Israel had light in their dwellings.
This is from the portion Bo. What it is about: Locusts, darkness and the death of the firstborn; the Passover lamb; the exodus from Egypt; the commandment of tefillin.
Other ways of counting
The tradition counts the same name in several ways. The main one is above: each letter is its number. The other eight are old and checkable too; each gives its own number, and many of them have a Torah word with the same number.
Final letters as 500–900 (mispar gadol) — 463.
Reduced, each letter to one digit (mispar katan) — 22. A Torah word with the same number is יחד — “together” (Genesis 13:6).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 49. A Torah word with the same number is מואב — “Moab, son of Lot” (Genesis 19:37).
Cumulative: a letter plus all letters before it (mispar kidmi) — 1741.
Squares of the letter values (mispar perati) — 162589.
Building: the sum grows with each letter (mispar bone’eh) — 1729.
The letters that come out are אסטצ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 160. A Torah word with the same number is כסף — “silver, money” (Genesis 13:2).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 936.
The number 463 appears in the classical books 1 time across 1 work. The earliest mention is שער הפסוקים (~1573).

The number of the day, every morning
Every date has a number too. Once a year it will match the number of your name — 463. The channel posts one number a day, one verse and the Torah page it lands on. Nothing after it, no mailing list.
Hebrew is written from right to left. תחנה has 4 letters: ת Tav, ח Chet, נ Nun, ה He. The first letter is Tav, the last is He.
For an engraving, a sign or a tattoo, show the spelling to someone who reads Hebrew: transliterating a name is a choice, not the only option.
The name תחנה does not stand as a word in the Pentateuch — as with most names, including many Tanakh names from the later books.
The verse of your name
The Pentateuch has no verse that begins with ת and ends with ה. The custom allows the whole Tanakh — the Prophets and the Writings have 41 such verses. The first of them is Joshua 21:42:
תהיינה הערים האלה עיר עיר ומגרשיה סביבתיה כן לכל הערים האלה
Each Hebrew letter has a number; a word's number is their sum (alef 1 … tav 400). The page is the remainder modulo 354: the Torah divided into 354 pages of 861 letters, as the lunar year has 354 days. Everything can be checked by hand.
