The name Nahamani in Hebrew letters is נחמני. 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.
נחמני
In short
Your name in Hebrew letters is נחמני. A Tanakh name: an Israelite (first in Nehemiah 7:7; 1 mention in the Tanakh). Meaning, per Strong’s dictionary (1890): “consolatory”. Adding up the numbers of its letters gives 158 — the same as the Torah word ספיח, “aftergrowth”. That number points to Torah page 158 of 354 — in the portion Vayakhel. What that portion is about: The Sabbath comes before the work on the Sanctuary; the people bring more than enough; Bezalel and the craftsmen build the Tabernacle. The verse that begins with the first letter of your name and ends with the last is Isaiah 32:9. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Nahamani” — this exact spelling is what was calculated: נחמני. 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 נחמני gives 158.
158
The number 158 is the Torah word ספיח — «aftergrowth» (Leviticus 25:5).
And he made the table of acacia-wood: two cubits was the length thereof, and a cubit the breadth thereof, and a cubit and a half the height thereof.
This is from the portion Vayakhel. What it is about: The Sabbath comes before the work on the Sanctuary; the people bring more than enough; Bezalel and the craftsmen build the Tabernacle.
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) — 158. A Torah word with the same number is ספיח — “aftergrowth” (Leviticus 25:5).
Reduced, each letter to one digit (mispar katan) — 23.
Cumulative: a letter plus all letters before it (mispar kidmi) — 626. A Torah word with the same number is עשרון — “tenth part” (Exodus 29:40).
Squares of the letter values (mispar perati) — 6764.
Building: the sum grows with each letter (mispar bone’eh) — 512. A Torah word with the same number is קדחת — “fever” (Leviticus 26:16).
The letters that come out are טסיטמ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 128. A Torah word with the same number is חלץ — “to pull out, remove” (Leviticus 14:40).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 730.
The number 158 appears in the classical books 3 times across 3 works. The earliest mention is שער הגלגולים (~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 — 158. 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. נחמני has 5 letters: נ Nun, ח Chet, מ Mem, נ Nun, י Yod. The first letter is Nun, the last is Yod.
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 נחמני 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 נ and ends with י. The custom allows the whole Tanakh — the Prophets and the Writings have 15 such verses. The first of them is Isaiah 32:9:
נשים שאננות קמנה שמענה קולי בנות בטחות האזנה אמרתי
The name נחמני has no such day. The numbers of the dates in a year cover 326 values out of 940, and 158 is not among them. Half of all names are like this — neither good nor bad, just a fact of counting.
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.
