מבשם
In short
Your name in Hebrew letters is מבשם. A Tanakh name: an Ishmaelite and an Israelite (first in Genesis 25:13; 3 mentions in the Tanakh). Meaning, per Strong’s dictionary (1890): “fragrant”. Adding up the numbers of its letters gives 382 — the same as the Torah word מבשם, “Mibsam, son of Ishmael”. That number points to Torah page 28 of 354 — in the portion Vayera. What that portion is about: Three visitors at Abraham's tent; the plea for Sodom; the birth of Isaac; the binding of Isaac on Mount Moriah. The verse that begins with the first letter of your name and ends with the last is Genesis 10:5. Each of these steps is laid out below with its sources. Every figure can be checked by hand.

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) — 942.
Reduced, each letter to one digit (mispar katan) — 13. A Torah word with the same number is אחד — “one” (Genesis 1:5).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 49. A Torah word with the same number is מואב — “Moab, son of Lot” (Genesis 19:37).
Cumulative: a letter plus all letters before it (mispar kidmi) — 1388.
Squares of the letter values (mispar perati) — 93204.
Building: the sum grows with each letter (mispar bone’eh) — 806. A Torah word with the same number is לעשות — “to do, make” (Genesis 2:3).
The letters that come out are ישבי — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 322. A Torah word with the same number is כבש — “male lamb” (Exodus 12:5).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 932.

מאלה נפרדו איי הגוים בארצתם איש ללשנו למשפחתם בגויהם
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.
