King Pandu consumed by a (Brahmana’s) curse, had five sons born unto him in the woods that are like five Indras. O son of Ambika, thou hast brought up those children and taught them everything. They are obedient to thy commands. Giving them back their just share of the kingdom, O sire, filled with joy, be thou happy with thy sons. Then, O monarch, thou shalt inspire confidence in both the gods and men.

In plain words: Vidura reminds King Dhritarashtra (son of Ambika) that his brother Pandu, under a curse, had five sons in the forest, the Pandavas, who are like the god Indra. Dhritarashtra raised and taught them, and they obey him, so Vidura urges him to give them back their fair share of the kingdom and be happy with his own sons, earning the trust of gods and people.
