The name Marc in Hebrew letters is מארק. 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.
מארק
In short
Your name in Hebrew letters is מארק. From the Roman name Marcus, most likely linked to Mars, the Roman god of war. In Hebrew it is written by sound. Adding up the numbers of its letters gives 341 — the same as the Torah word אשם, “guilt, guilt offering”. That number points to Torah page 341 of 354 — in the portion Ki Tavo. What that portion is about: “When you enter”: the first fruits and the declaration; the stones on Mount Ebal; blessings and admonitions. The verse that begins with the first letter of your name and ends with the last is Isaiah 29:21. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Marc” — this exact spelling is what was calculated: מארק. 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 מארק gives 341.
341
The number 341 is the Torah word אשם — «guilt, guilt offering» (Genesis 26:10).
HaShem will cause thee to be smitten before thine enemies; thou shalt go out one way against them, and shalt flee seven ways before them; and thou shalt be a horror unto all the kingdoms of the earth.
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.
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) — 341. A Torah word with the same number is אשם — “guilt, guilt offering” (Genesis 26:10).
Reduced, each letter to one digit (mispar katan) — 8. A Torah word with the same number is אהב — “to love” (Genesis 22:2).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 53. A Torah word with the same number is אבן — “stone” (Genesis 2:12).
Cumulative: a letter plus all letters before it (mispar kidmi) — 1536.
Squares of the letter values (mispar perati) — 51601.
Building: the sum grows with each letter (mispar bone’eh) — 663.
The letters that come out are יתגד — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 417. A Torah word with the same number is זית — “olive” (Genesis 8:11).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 887.
The number 341 appears in the classical books 8 times across 7 works. The earliest mention is בעל הטורים על התורה (~1300).

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 מארק 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 מ and ends with ק. The custom allows the whole Tanakh — the Prophets and the Writings have 4 such verses. The first of them is Isaiah 29:21:
«HaShem will cause thee to be smitten before thine enemies; thou shalt go out one way against them, and shalt flee seven ways before them; and thou shalt be a horror unto all the kingdoms of the earth.»
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.
