Pearls for the Sage's Mouth

From D13.20.5, The Fourth Banquet. It illustrates D13.20.5.54–58:

D13.20.5.54
When Bozorgmehr had ended all his speech,The gathered sages found him past their reach.
D13.20.5.55
Their counsels, weighed beside his words that day,Seemed lamps grown pale beneath the morning ray.
D13.20.5.56
Anooshirvan heard; his spirit rose in light;His former greatness climbed to greater height.
D13.20.5.57
His eyes grew wet; he bade bright pearls be brought,And filled the sage’s mouth for what he taught.
D13.20.5.58
The gathering’s lips were full of thanks and praise;Then all departed, blessing all his ways.
