The name Jediael in Hebrew letters is ידיעאל. 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.
ידיעאל
In short
Your name in Hebrew letters is ידיעאל. A Tanakh name: the name of three Israelites (first in 1 Chronicles 7:6; 6 mentions in the Tanakh). Meaning, per Strong’s dictionary (1890): “knowing God”. Adding up the numbers of its letters gives 125 — the same as the Torah word ענה, “to answer, afflict”. That number points to Torah page 125 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 Deuteronomy 1:38. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Jediael” — this exact spelling is what was calculated: ידיעאל. 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 ידיעאל gives 125.
125
The number 125 is the Torah word ענה — «to answer, afflict» (Genesis 18:27).
And HaShem said unto Moses: 'Go down, charge the people, lest they break through unto HaShem to gaze, and many of them perish.
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”.
The same number, 125, is given by these Tanakh names:

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) — 125. A Torah word with the same number is ענה — “to answer, afflict” (Genesis 18:27).
Reduced, each letter to one digit (mispar katan) — 17. A Torah word with the same number is טוב — “good” (Genesis 1:4).
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) — 551. A Torah word with the same number is מורשה — “possession, heritage” (Exodus 6:8).
Squares of the letter values (mispar perati) — 6017.
Building: the sum grows with each letter (mispar bone’eh) — 362. A Torah word with the same number is משכב — “bed” (Genesis 49:4).
The letters that come out are מקמזתכ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 607. A Torah word with the same number is בהרת — “bright spot” (Leviticus 13:2).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 789. A Torah word with the same number is תשפט — “you shall judge” (Leviticus 19:15).
The number 125 appears in the classical books 10 times across 8 works. The earliest mention is ספר הפליאה (~1390).

The name ידיעאל 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 ידיעאל these are י and ל. The Pentateuch has exactly one such verse — Deuteronomy 1:38:
יהושע בן נון העמד לפניך הוא יבא שמה אתו חזק כי הוא ינחלנה את ישראל
This is from the portion Devarim. What it is about: Moses begins his address in the plains of Moab: judges, spies, forty years of wandering, the victories over Sihon and Og.
Any name written in Hebrew letters is a number: ידיעאל = 125. And every date has a number of its own. There is a day in the year when the two coincide.
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.
