O sire, preserving thy fame unsullied, cherish thou the children of Pandu, afflicted as they are with the sufferings of exile. O descendant of Kuru, make peace with the sons of Pandu. Let not thy foes discover thy holes. They all, O god among men, are devoted to truth. O king of men, withdraw Duryodhana from his evil ways.

In plain words: Vidura urges Dhritarashtra to keep his good name by caring for the sons of Pandu, who are suffering in exile. He asks the king to make peace with them, not let enemies find his weak spots, and pull his son Duryodhana away from his wicked ways, since the Pandavas are all devoted to truth.
