Charity
Purity

You almost got it Those lazy ones click the spoiler:

Spoiler Alert, click show to read: 

upper: ašha (holiness/truth/light...) left: eranšhahr (all iran-empire) right: arta (truth, fire, order...) lower: "ey" (for decorative reasons) and "ahura" (wisdom)

Anyway I can provide different shields for the persians in the vector graphics way I made this banner, that you may then easily turn into right textures properly.
Just write a wishlist what dimensions, etc. if you will
