The name Sidoine in Hebrew letters is סידואן. 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.
סידואן
In short
Your name in Hebrew letters is סידואן. The name comes from Latin “Sidonius”, “from Sidon”, an old Phoenician city in today's Lebanon. Sidonius Apollinaris was a Gallo-Roman poet of the 5th century. This form of the name is used in France. In Hebrew it is written by sound. Adding up the numbers of its letters gives 131 — the same as the Torah word מצא, “to find”. That number points to Torah page 131 of 354 — in the portion Mishpatim. What that portion is about: Laws of the servant, damages, theft and pledges; “an eye for an eye” as compensation; the sabbatical year; “we will do and we will hear”. The verse that begins with the first letter of your name and ends with the last is Joshua 12:2. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Sidoine” — this exact spelling is what was calculated: סידואן. 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 סידואן gives 131.
131
The number 131 is the Torah word מצא — «to find» (Genesis 2:20).
For Mine angel shall go before thee, and bring thee in unto the Amorite, and the Hittite, and the Perizzite, and the Canaanite, the Hivite, and the Jebusite; and I will cut them off.
This is from the portion Mishpatim. What it is about: Laws of the servant, damages, theft and pledges; “an eye for an eye” as compensation; the sabbatical year; “we will do and we will hear”.
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) — 781. A Torah word with the same number is ממשאת — “than the portions of” (Genesis 43:34).
Reduced, each letter to one digit (mispar katan) — 23.
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 50. A Torah word with the same number is כל — “all, every” (Genesis 1:21).
Cumulative: a letter plus all letters before it (mispar kidmi) — 537. A Torah word with the same number is מטבעתיו — “by its rings” (Exodus 28:28).
Squares of the letter values (mispar perati) — 6253.
Building: the sum grows with each letter (mispar bone’eh) — 496. A Torah word with the same number is צרור — “bundle, pouch” (Genesis 42:35).
The letters that come out are חמקפתט — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 637. A Torah word with the same number is לראות — “to see” (Genesis 2:19).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 803. A Torah word with the same number is באתת — “with the banners” (Numbers 2:2).
The number 131 appears in the classical books 27 times across 18 works. The earliest mention is ספר קרניים (~1400).

The number of the day, every morning
Every date has a number too. Once a year it will match the number of your name — 131. The channel posts one number a day, one verse and the Torah page it lands on. Nothing after it, no mailing list.

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 סידואן 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 ס and ends with נ. The custom allows the whole Tanakh — the Prophets and the Writings have 2 such verses. The first of them is Joshua 12:2:
סיחון מלך האמרי היושב בחשבון משל מערוער אשר על שפת נחל ארנון ותוך הנחל וחצי הגלעד ועד יבק הנחל גבול בני עמון
Any name written in Hebrew letters is a number: סידואן = 131. And every date has a number of its own. There is a day in the year when the two coincide.
«For Mine angel shall go before thee, and bring thee in unto the Amorite, and the Hittite, and the Perizzite, and the Canaanite, the Hivite, and the Jebusite; and I will cut them off.»
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.
