The name Jabal in Hebrew letters is יבל. 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.
יבל
In short
Your name in Hebrew letters is יבל. A Tanakh name: an antediluvian (first in Genesis 4:20; 1 mention in the Tanakh). Adding up the numbers of its letters gives 42 — the same as the Torah word חדל, “to cease”. That number points to Torah page 42 of 354 — in the portion Toldot. What that portion is about: The birth of Esau and Jacob; the birthright sold for lentil stew; Isaac's wells; Jacob receives the blessing. The verse that begins with the first letter of your name and ends with the last is Deuteronomy 1:38. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Jabal” — this exact spelling is what was calculated: יבל. 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.
Adding up the letters of the name יבל gives 42.
42
The number 42 is the Torah word חדל — «to cease» (Genesis 11:8).
And Isaac digged again the wells of water, which they had digged in the days of Abraham his father; for the Philistines had stopped them after the death of Abraham; and he called their names after the names by which his father had called them.
This is from the portion Toldot. What it is about: The birth of Esau and Jacob; the birthright sold for lentil stew; Isaac's wells; Jacob receives the blessing.
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) — 42. A Torah word with the same number is חדל — “to cease” (Genesis 11:8).
Reduced, each letter to one digit (mispar katan) — 6. A Torah word with the same number is בד — “alone, apart” (Genesis 2:18).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 24. A Torah word with the same number is חוי — “Hivite” (Genesis 10:17).
Cumulative: a letter plus all letters before it (mispar kidmi) — 163. A Torah word with the same number is אצבע — “finger” (Exodus 8:15).
Squares of the letter values (mispar perati) — 1004.
Building: the sum grows with each letter (mispar bone’eh) — 64. A Torah word with the same number is נטה — “to stretch out, pitch” (Genesis 12:8).
The letters that come out are משכ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 360. A Torah word with the same number is שני — “second” (Genesis 1:8).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 506. A Torah word with the same number is שור — “ox” (Genesis 32:6).
The number 42 appears in the classical books 31 times across 22 works. The earliest mention is ספר הפליאה (~1390).

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 יבל these are י and ל. The Pentateuch has exactly one such verse — Deuteronomy 1:38:
יהושע בן נון העמד לפניך הוא יבא שמה אתו חזק כי הוא ינחלנה את ישראל
This is from the portion Devarim. What it is about: Moses begins his address in the plains of Moab: judges, spies, forty years of wandering, the victories over Sihon and Og.
The name יבל has no such day. The numbers of the dates in a year cover 326 values out of 940, and 42 is not among them. Half of all names are like this — neither good nor bad, just a fact of counting.
Add a date of birth and the verse of meeting from that week's portion is added to the reading.
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.
