Day 14 covers all of Chapter 9, The Assurance of Future Buddhahood of the Śrāvakas Who Have Something More to Learn and the Śrāvakas Who Have Nothing More to Learn and the first part of Chapter 10, The Teacher of the Dharma

In Chapter 9, the Śrāvakas, having heard of their future Buddhahood, sing:

You, the World-Honored One, are the light of wisdom.
Hearing from you
That we are assured of our future Buddhahood,
We are as joyful as if we were sprinkled with nectar.

Rejoicing in the Lotus Sutra in Chapter 10:

The Buddha said to Medicine-King:
“If after my extinction anyone rejoices, even on a moment’s thought, at hearing even a gāthā or a phrase of the Sūtra of the Lotus Flower of the Wonderful Dharma, I also will assure him of his future attainment of Anuttara-samyak-saṃbodhi.”

Compassion of the Bodhisattvas:

Anyone who keeps
The Sūtra of the Lotus Flower of the Wonderful Dharma
Should be considered to have given up his pure world and come here
Out of his compassion towards all living beings.

The Buddha’s messengers:

The good men or women who expound even a phrase of the Sūtra of the Lotus Flower of the Wonderful Dharma even to one person even in secret after my extinction, know this, are my messengers. They are dispatched by me. They do my work.

A sinful person:

Medicine-King! An evil man who speaks ill of me in my presence with evil intent for as long as a kalpa is not as sinful as the person who reproaches laymen or monks with even a single word of abuse for their reading and reciting the Sūtra of the Lotus Flower of the Wonderful Dharma.

And in gāthās:

Whoever for as long as a kalpa,
With evil intent and flushed face,
Speaks ill of me,
Will incur immeasurable retributions.
Whoever for even a moment
Reproaches those who read, recite and keep
The Sūtra of the Lotus Flower of the Wonderful Dharma
Will incur even more retributions.
