The name Josiah in Hebrew letters is יאשיהו. 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.
יאשיהו
In short
Your name in Hebrew letters is יאשיהו. Adding up the numbers of its letters gives 332 — the same as the Torah word לבש, “wrap around, i.e.”. That number points to Torah page 332 of 354 — in the portion Ki Teitzei. What that portion is about: “When you go out”: seventy-four commandments — the bird's nest, honest weights, divorce, remembering Amalek. The verse that begins with the first letter of your name and ends with the last is Genesis 9:27. 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 יאשיהו gives 332.
332
The number 332 is the Torah word לבש — «wrap around, i.e.» (Genesis 3:21).
The number 332, as the remainder modulo 354, points to Torah page 332 in the book of Devarim (Deuteronomy). These are its opening words:
כי עשתה נבלה בישראל לזנות בית אביה ובערת …
The verse this place falls on is Devarim (Deuteronomy) 22:21:
וְהוֹצִיאוּ אֶת־הנער אֶל־פֶּתַח בֵּית־אָבִיהָ וּסְקָלוּהָ אַנְשֵׁי עִירָהּ בָּאֲבָנִים וָמֵתָה כִּי־עָשְׂתָה נְבָלָה בְּיִשְׂרָאֵל לִזְנוֹת בֵּית אָבִיהָ וּבִעַרְתָּ הָרָע מִקִּרְבֶּךָ ס
then they shall bring out the damsel to the door of her father's house, and the men of her city shall stone her with stones that she die; because she hath wrought a wanton deed in Israel, to play the harlot in her father's house; so shalt thou put away the evil from the midst of thee.
This is from the portion Ki Teitzei. What it is about: “When you go out”: seventy-four commandments — the bird's nest, honest weights, divorce, remembering Amalek.
The same number, 332, is given by these biblical names:
יאשיהו · שוכו · מבצר
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) — 332. A Torah word with the same number is לבש — “wrap around, i.e.” (Genesis 3:21).
Reduced, each letter to one digit (mispar katan) — 17. A Torah word with the same number is טוב — “good” (Genesis 1:4).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 53. A Torah word with the same number is אבן — “a stone” (Genesis 2:12).
Cumulative: a letter plus all letters before it (mispar kidmi) — 1242.
Squares of the letter values (mispar perati) — 90262.
Building: the sum grows with each letter (mispar bone’eh) — 1311.
The word that comes out is מתבמצפ. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 652. A Torah word with the same number is מרבית — “a multitude” (Leviticus 25:37).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 529.
The number 332 appears in the classical books 5 times across 3 works. The earliest mention is מגלה עמוקות (~1637).
The name יאשיהו 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 יאשיהו these are י and ו. The Pentateuch has 7 such verses. The first of them is Genesis 9:27:
יפת אלהים ליפת וישכן באהלי שם ויהי כנען עבד למו
This is from the portion Noach. What it is about: The flood and the ark; the rainbow as a sign of the covenant; the tower of Babel; ten generations from Noah to Abraham.

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.
