The name John in Hebrew letters is יוחנן. 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.
יוחנן
In short
Your name in Hebrew letters is יוחנן. Adding up the numbers of its letters gives 124 — the same as the Torah word עדן, “Eden, the region of Adam's home”. That number points to Torah page 124 of 354 — in the portion Yitro. What that portion is about: Jethro's counsel on judges; standing at Sinai; the Ten Utterances; “you shall not make yourself an idol”. The verse that begins with the first letter of your name and ends with the last is Exodus 1:3. Each of these steps is laid out below with its sources. There are no predictions or judgments here — only the text of the Torah and arithmetic you can check.
Adding up the letters of the name יוחנן gives 124.
124
The number 124 is the Torah word עדן — «Eden, the region of Adam's home» (Genesis 2:8).
The number 124, as the remainder modulo 354, points to Torah page 124 in the book of Shmot (Exodus). These are its opening words:
אלה הדברים אשר תדבר אל בני ישראל ויבא …
The verse this place falls on is Shmot (Exodus) 19:6:
וְאַתֶּם תִּהְיוּ־לִי מַמְלֶכֶת כֹּהֲנִים וְגוֹי קָדוֹשׁ אֵלֶּה הַדְּבָרִים אֲשֶׁר תְּדַבֵּר אֶל־בְּנֵי יִשְׂרָאֵל
and ye shall be unto Me a kingdom of priests, and a holy nation. These are the words which thou shalt speak unto the children of Israel.'
This is from the portion Yitro. What it is about: Jethro's counsel on judges; standing at Sinai; the Ten Utterances; “you shall not make yourself an idol”.
The same number, 124, is given by these biblical names:
יוחנן · עדן · אלעוזי · ידלף
Nine 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) — 774.
Reduced, each letter to one digit (mispar katan) — 25. A Torah word with the same number is כה — “like this, i.e. by implication” (Genesis 15:5).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 52. A Torah word with the same number is בן — “a son” (Genesis 3:16).
Cumulative: a letter plus all letters before it (mispar kidmi) — 502. A Torah word with the same number is בשר — “flesh” (Genesis 2:21).
Squares of the letter values (mispar perati) — 5200.
Building: the sum grows with each letter (mispar bone’eh) — 248. A Torah word with the same number is אברהם — “Abraham, the later name of Abram” (Genesis 17:5).
The word that comes out is מפסטט. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 198. A Torah word with the same number is צחק — “to laugh outright” (Genesis 17:17).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 662.
The number 124 appears in the classical books 6 times across 6 works. The earliest mention is כל בו (~1300).

Every letter of the name explained, the words and namesakes with references, the Hebrew date, the letter and tribe of the month, the day 861 of your life, the psalm by age, the attestations from 834 works — a PDF built the moment you pay.
The name יוחנן 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
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 יוחנן these are י and נ. The Pentateuch has 4 such verses. The first of them is Exodus 1:3:
יששכר זבולן ובנימן
This is from the portion Shemot. What it is about: Slavery in Egypt; Moses in the basket on the Nile; the burning bush and the Name; the first audience with Pharaoh.

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.
