חיין
In short
Your name in Hebrew letters is חיין. Adding up the numbers of its letters gives 78 — the same as the Torah word לחם, “bread, food”. That number points to Torah page 78 of 354 — in the portion Miketz. What that portion is about: Pharaoh's dreams of seven cows and seven ears; Joseph rules Egypt; the brothers come for grain; the cup in Benjamin's sack. The verse that begins with the first letter of your name and ends with the last is Joshua 13:17. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Kheyn” — this exact spelling is what was calculated: חיין. 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 חיין gives 78.
78
The number 78 is the Torah word לחם — «bread, food» (Genesis 3:19).
And other money have we brought down in our hand to buy food. We know not who put our money in our sacks.'
This is from the portion Miketz. What it is about: Pharaoh's dreams of seven cows and seven ears; Joseph rules Egypt; the brothers come for grain; the cup in Benjamin's sack.
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) — 728. A Torah word with the same number is תשכח — “you forget” (Deuteronomy 4:9).
Reduced, each letter to one digit (mispar katan) — 15. A Torah word with the same number is זוב — “to flow” (Exodus 3:8).
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) — 341. A Torah word with the same number is אשם — “guilt, guilt offering” (Genesis 26:10).
Squares of the letter values (mispar perati) — 2764.
Building: the sum grows with each letter (mispar bone’eh) — 132. A Torah word with the same number is בלק — “Balak, king of Moab” (Numbers 22:2).
The letters that come out are סממט — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 149. A Torah word with the same number is קדמה — “east of” (Genesis 2:14).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 564. A Torah word with the same number is כדרלעמר — “Chedorlaomer, king of Elam” (Genesis 14:1).
The number 78 appears in the classical books 33 times across 16 works. The earliest mention is ספר קרניים (~1400).

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 חיין 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 ח and ends with נ. The custom allows the whole Tanakh — the Prophets and the Writings have 8 such verses. The first of them is Joshua 13:17:
חשבון וכל עריה אשר במישר דיבון ובמות בעל ובית בעל מעון
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.
