The name Tubal in Hebrew letters is תבל. 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.
תבל
In short
Your name in Hebrew letters is תבל. A Tanakh name: a postdiluvian patriarch (first in Genesis 10:2; 8 mentions in the Tanakh). Adding up the numbers of its letters gives 432. That number points to Torah page 78 of 354 — in the portion Miketz. What that portion is about: Pharaoh's dreams of seven cows and seven ears; Joseph rules Egypt; the brothers come for grain; the cup in Benjamin's sack. The verse that begins with the first letter of your name and ends with the last is Deuteronomy 28:47. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Tubal” — this exact spelling is what was calculated: תבל. 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.
And other money have we brought down in our hand to buy food. We know not who put our money in our sacks.'
This is from the portion Miketz. What it is about: Pharaoh's dreams of seven cows and seven ears; Joseph rules Egypt; the brothers come for grain; the cup in Benjamin's sack.
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) — 432.
Reduced, each letter to one digit (mispar katan) — 9. A Torah word with the same number is בוא — “to come, enter” (Genesis 2:19).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 36. A Torah word with the same number is אלה — “these” (Genesis 2:4).
Cumulative: a letter plus all letters before it (mispar kidmi) — 1603.
Squares of the letter values (mispar perati) — 160904.
Building: the sum grows with each letter (mispar bone’eh) — 1234.
The letters that come out are אשכ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 321. A Torah word with the same number is אשך — “testicle” (Leviticus 21:20).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 892.
The number 432 appears in the classical books 3 times across 3 works. The earliest mention is בעל הטורים על התורה (~1300).

The number of the day, every morning
Every date has a number too. Once a year it will match the number of your name — 432. 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. תבל has 3 letters: ת Tav, ב Bet, ל Lamed. The first letter is Tav, the last is Lamed.
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 תבל appears in the Torah as a word 3 times. The first time is Genesis 10:2. Another 1 time it stands with prefixes — “and”, “in”, “the”.
The verse of your name
There is a custom: at the end of the prayer one says a Torah verse that begins with the first letter of one's name and ends with its last. For תבל these are ת and ל. The Pentateuch has exactly one such verse — Deuteronomy 28:47:
תחת אשר לא עבדת את ה׳ אלהיך בשמחה ובטוב לבב מרב כל
This is from the portion Ki Tavo. What it is about: “When you enter”: the first fruits and the declaration; the stones on Mount Ebal; blessings and admonitions.
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.
