Where do I obtain the high level spells like hastega, renew, and holy in Final Fantasy XII?

Question

I just found the secret guy in Necrohol, so I was wondering where the rest of the spells are.

I've completed the entire game except the last part - The Airship Bahamut.

I'm going through and completeing all the marks while I level up. I found Hastega, and I found Scathe, but I can't find stuff like Renew or Holy, or Aldor, or Shock, or etc.

Answer 1

Most of the better magicks are not available until late in the game. I believe those high-end spells show up upon your return from the Pharos.

EDIT -
Renew - Dalmasca Westersand
Holy - Balfonheim Port
Ardor - Barheim Passage
Shock - Balfonheim Port
Scourge - Balfonheim Port
Flare - Balfonheim Port
