The name Gal in Hebrew letters is גל. 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.
גל
In short
Your name in Hebrew letters is גל. Adding up the numbers of its letters gives 33 — the same as the Torah word גל, “heap of stones”. That number points to Torah page 33 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 2 Samuel 5:2. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Gal” — this exact spelling is what was calculated: גל. 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 גל gives 33.
33
The number 33 is the Torah word גל — «heap of stones» (Genesis 31:46).
And they came to the place which G-d had told him of; and Abraham built the altar there, and laid the wood in order, and bound Isaac his son, and laid him on the altar, upon the wood.
This is from the portion Vayera. What it is about: Three visitors at Abraham's tent; the plea for Sodom; the birth of Isaac; the binding of Isaac on Mount Moriah.
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) — 33. A Torah word with the same number is גל — “heap of stones” (Genesis 31:46).
Reduced, each letter to one digit (mispar katan) — 6. A Torah word with the same number is בד — “alone, apart” (Genesis 2:18).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 15. A Torah word with the same number is זוב — “to flow” (Exodus 3:8).
Cumulative: a letter plus all letters before it (mispar kidmi) — 111. A Torah word with the same number is אלף — “thousand” (Genesis 20:16).
Squares of the letter values (mispar perati) — 909.
Building: the sum grows with each letter (mispar bone’eh) — 36. A Torah word with the same number is אלה — “these” (Genesis 2:4).
The letters that come out are רכ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 220. A Torah word with the same number is טהור — “pure, clean” (Genesis 7:2).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 157. A Torah word with the same number is זקן — “old, elder” (Genesis 18:11).
The number 33 appears in the classical books 7 times across 7 works. The earliest mention is שיטה מקובצת על הש"ס (~1550).

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 גל appears in the Torah as a word 1 time. The first time is Genesis 31:46. Another 6 times it stands with prefixes — “and”, “in”, “the”.
The verse of your name
The Pentateuch has no verse that begins with ג and ends with ל. The custom allows the whole Tanakh — the Prophets and the Writings have 8 such verses. The first of them is 2 Samuel 5:2:
גם אתמול גם שלשום בהיות שאול מלך עלינו אתה הייתה מוציא והמבי את ישראל ויאמר ה׳ לך אתה תרעה את עמי את ישראל ואתה תהיה לנגיד על ישראל
«And they came to the place which G-d had told him of; and Abraham built the altar there, and laid the wood in order, and bound Isaac his son, and laid him on the altar, upon the wood.»
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.
