The name Detlef in Hebrew letters is דטלף. 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.
דטלף
In short
Your name in Hebrew letters is דטלף. Detlef is a personal name of Germanic origin: it comes from the word thiot + leib, which means “people + heir”. Today this name is common in Germany. In Hebrew it is written by sound. 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 Jeremiah 9:21. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Detlef” — this exact spelling is what was calculated: דטלף. 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.
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) — 843. A Torah word with the same number is המשבצות — “the settings” (Exodus 28:25).
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) — 42. A Torah word with the same number is חדל — “to cease” (Genesis 11:8).
Cumulative: a letter plus all letters before it (mispar kidmi) — 565. A Torah word with the same number is ושטרים — “and officers” (Deuteronomy 1:15).
Squares of the letter values (mispar perati) — 7397.
Building: the sum grows with each letter (mispar bone’eh) — 183.
The letters that come out are קנכו — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 176. A Torah word with the same number is פוץ — “to scatter” (Genesis 10:18).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 1008. A Torah word with the same number is תרבות — “brood, offspring” (Numbers 32:14).
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.

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 דטלף 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 ד and ends with פ. The custom allows the whole Tanakh — the Prophets and the Writings have 2 such verses. The first of them is Jeremiah 9:21:
דבר כה נאם ה׳ ונפלה נבלת האדם כדמן על פני השדה וכעמיר מאחרי הקצר ואין מאסף
«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.»
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.
