527-540 And Apollo sware also:
Verily I will make you only to be an omen for the immortals and all
alike, trusted and honoured by my heart. Moreover, I will give you a
splendid staff of riches and wealth: it is of gold, with three branches,
and will keep you scatheless, accomplishing every task, whether of words
or deeds that are good, which I claim to know through the utterance of
Zeus. But as for sooth-saying, noble, heaven-born child, of which you
ask, it is not lawful for you to learn it, nor for any other of the
deathless gods: only the mind of Zeus knows that. I am pledged and have
vowed and sworn a strong oath that no other of the eternal gods save
I should know the wise-hearted counsel of Zeus. And do not you, my
brother, bearer of the golden wand, bid me tell those decrees which
all-seeing Zeus intends.
