A brief prayer from PGM I.197—222, “the prayer of deliverance for the first-begotten and first-born god”.  This is a prayer directed to Aiōn presenting to the world as Hēlios seeking help and succor in one’s hour of need, to be said facing the Sun when one is seized in trouble or otherwise forced to do so.  This prayer has many similarities in tone, purpose, and the use of barbarous words as from PGM IV.1167—1226 “the stele that is useful for all things”, which I myself call the Stele of Aiōn.  Although Betz gives his translation, I present my own with corrections based on Preisendanz below.  First introduced in this April 2020 post.

I call upon you, o Lord!
Hear me, o holy god who rests among the holy ones,
at whose side the glorious angels stand forever!
I call upon you, o Forefather, and I beseech you, o Aiōn of Aiōns,
o unmoved ruler, eternal ruler of the celestial pole,
you who are established upon the seven-part heavens!
ΧΑΩ ΧΑΩ ΧΑ ΟΥΦ ΧΘΕΘΩΝΙΜΕΕΘΗΧΡΙΝΙΑ ΜΕΡΟΥΜ Ι ΑΛΔΑ ΖΑΩ ΒΛΑΘΑΜΜΑΧΩΘ ΦΡΙΞΑ ΗΚΕΩΦΥΗΙΔΡΥΜΗΩ ΦΕΡΦΡΙΘΩ ΙΑΧΘΩ ΨΥΧΕΩ ΦΙΡΙΘΜΕΩ ΡΩΣΕΡΩΘ ΘΑΜΑΣΤΡΑ ΦΑΤΙΡΙ ΤΑΩΧ ΙΑΛΘΕΜΕΑΧΕ
Υou who hold fast to the root of the cosmos!
you who possess the powerful name hallowed by all the angels!
Hear me, you who have established the mighty decans and archangels,
beside whom stands untold myriads of angels!
You have been exalted to Heaven by the Lord,
having borne witness to your wisdom and having praised your power,
having declared that your strength is as his in every way in this world.

I call upon you, o Lord of the All, in my hour of need;
hear me, for my soul is distressed, and I am troubled and in want of everything.
Come to me, who you are lord over all the angels;
shield me against all excess of power of the aerial Daimōn and of Fate.
O Lord, hear me, for I call upon you by your secret name
that reaches from the heights of Heaven to the depths of the Abyss:

Rescue me in an hour of need!

The two sets of barbarous words, transliterated into Roman text and with my own aspirations of <h> thrown in for good measure where I find them to be appropriate:
