'tassa' is Genitive-Dative, so 'his' or 'to him'. See my
interpretation below.

Well, before Enlightenment Buddha discovered that happiness is neither
bad nor good, if you don't cling to it, and through jhanas went to
Awakening.
It seems that the point here is that a person partaking alms-food, i.e.
bhikkhu, should take care before being immoral, as it's
dangerous for an immoral person to live on alms-food given in faith.
Let me tell you, monks, let me answer you, monks, that it better for a
person, immoral, wicked, unclean and suspect in conduct, secretive in
deeds, not a contemplative though claiming to be one, not leading the
holy life though claiming to do so, inwardly rotten, oozing with
desire, filthy by nature, if a strong man, having opened the mouth
with a red-hot iron spike, were to hurl into the mouth a red-hot iron
ball, burning, blazing, glowing; and it would burn this person's lip,
and would burn the mouth, and would burn the tongue, and would burn
the throat, and would burn the chest, and having been received by
the lower intestine, it would be expelled from the lower part of
the body.
Why so? For, monks, because of that he would suffer death, or
death-like agony, but on account of that, on the break-up of the body
after death, he won't be reborn in a place of woe, a realm of misery,
a state of punishment, a purgatory.
And monks, for such a person, immoral, wicked, unclean and suspect in
conduct, secretive in deeds, not a contemplative though claiming to be
one, not leading the holy life though claiming to do so, inwardly
rotten, oozing with desire, filthy by nature, who eats the food
received on alms-round given in faith by wealthy kshatriya, brahmins,
or householders, for him, monks, there is a long-term harm and
suffering, and on the break-up of the body after death, he is reborn
in a place of woe, a realm of misery, a state of punishment, a
purgatory.
