The name Jobab in Hebrew letters is יובב. 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.
יובב
In short
Your name in Hebrew letters is יובב. A Tanakh name: the name of two Israelites and three foreigners (first in Genesis 10:29; 9 mentions in the Tanakh). Adding up the numbers of its letters gives 20 — the same as the Torah word היה, “to be, become”. That number points to Torah page 20 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 Exodus 15:6. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Jobab” — this exact spelling is what was calculated: יובב. 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 יובב gives 20.

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.
with finals and ordinal — 20. A Torah word with the same number is היה — “to be, become” (Genesis 1:2).
Reduced, each letter to one digit (mispar katan) — 11. A Torah word with the same number is חג — “festival” (Exodus 10:9).
Cumulative: a letter plus all letters before it (mispar kidmi) — 82. A Torah word with the same number is לבן — “Laban, brother of Rebekah” (Genesis 24:29).
Squares of the letter values (mispar perati) — 144. A Torah word with the same number is קדם — “east, ancient time” (Genesis 2:8).
Building: the sum grows with each letter (mispar bone’eh) — 64. A Torah word with the same number is נטה — “to stretch out, pitch” (Genesis 12:8).
The letters that come out are מפשש — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 720. A Torah word with the same number is ישית — “he will set” (Genesis 46:4).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 856. A Torah word with the same number is תתנו — “you shall give” (Genesis 34:9).

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 יובב these are י and ב. The Pentateuch has 5 such verses. The first of them is Exodus 15:6:
ימינך ה׳ נאדרי בכח ימינך ה׳ תרעץ אויב
This is from the portion Beshalach. What it is about: The parting of the sea and the song of Moses and Miriam; manna and quail; water from the rock; the war with Amalek.
«And they turned back, and came to En-mishpat--the same is Kadesh--and smote all the country of the Amalekites, and also the Amorites, that dwelt in Hazazon-tamar.»
