The name Joy in Hebrew letters is ג׳וי. 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.
ג׳וי
In short
Your name in Hebrew letters is ג׳וי. The English word joy, from Old French joie and Latin gaudia. It has been used as a girl's name since the 17th century. In Hebrew it is written by sound. Adding up the numbers of its letters gives 19 — the same as the Torah word גוי, “nation”. That number points to Torah page 19 of 354 — in the portion Lech Lecha. What that portion is about: “Go forth”: Abraham leaves Haran; the promise of land and offspring; the covenant between the pieces; circumcision. The verse that begins with the first letter of your name and ends with the last is Genesis 23:4. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Joy” — this exact spelling is what was calculated: ג׳וי. 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 ג׳וי gives 19.

This is from the portion Chayei Sarah. What it is about: Sarah's death and the purchase of the cave of Machpelah; the servant seeks a wife for Isaac; Rebecca at the well; Abraham's death.
