Therefore, he that is wise, should not resort to it even in jest. O son of Pratipa, at the time of that gambling match I told thee, O king—this is not proper. But, O son of Vichitravirya, like medicine to a sick man, those words of mine were not agreeable to thee. O king, thou desirest to vanquish the sons of Pandu, who are just as peacocks of variegated plumage, whereas thy sons are all as crows. Forsaking lions thou art protecting jackals! O king, when the time cometh, thou wilt have to grieve for all this.

In plain words: Vidura says a wise person should not gamble even as a joke. He reminds the king that he warned him at the dice game, but like bitter medicine for a sick man, the warning was not welcome. He says the king wants to defeat the Pandavas, who are like beautiful peacocks, while his own sons are like crows, and that he is protecting jackals while abandoning lions, and will grieve for it later.
