The name Mahseiah in Hebrew letters is מחסיה. 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.
מחסיה
In short
Your name in Hebrew letters is מחסיה. A Tanakh name: an Israelite (first in Jeremiah 32:12; 2 mentions in the Tanakh). Meaning, per Strong’s dictionary (1890): “refuge in God”. Adding up the numbers of its letters gives 123. That number points to Torah page 123 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 Genesis 7:8. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Mahseiah” — this exact spelling is what was calculated: מחסיה. 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 מחסיה gives 123.
Thou wilt surely wear away, both thou, and this people that is with thee; for the thing is too heavy for thee; thou art not able to perform it thyself alone.
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”.
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) — 123.
Reduced, each letter to one digit (mispar katan) — 24. A Torah word with the same number is חוי — “Hivite” (Genesis 10:17).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 51. A Torah word with the same number is אכל — “to eat” (Genesis 2:16).
Cumulative: a letter plus all letters before it (mispar kidmi) — 506. A Torah word with the same number is שור — “ox” (Genesis 32:6).
Squares of the letter values (mispar perati) — 5389.
Building: the sum grows with each letter (mispar bone’eh) — 437. A Torah word with the same number is משבצה — “filigree setting” (Exodus 28:11).
The letters that come out are יסחמצ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 208. A Torah word with the same number is יצחק — “Isaac, son of Abraham” (Genesis 17:19).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 644. A Torah word with the same number is מרבבת — “from myriads of” (Deuteronomy 33:2).
The number 123 appears in the classical books 6 times across 6 works. The earliest mention is עץ חיים (~1573).

The number of the day, every morning
Every date has a number too. Once a year it will match the number of your name — 123. The channel posts one number a day, one verse and the Torah page it lands on. Nothing after it, no mailing list.
Hebrew is written from right to left. מחסיה has 5 letters: מ Mem, ח Chet, ס Samekh, י Yod, ה He. The first letter is Mem, the last is He.
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 מחסיה 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 מחסיה these are מ and ה. The Pentateuch has 16 such verses. The first of them is Genesis 7:8:
מן הבהמה הטהורה ומן הבהמה אשר איננה טהרה ומן העוף וכל אשר רמש על האדמה
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.

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.
