That prosperity, however, which depends on both strength and softness, descends to sons and grandsons intact. Let, therefore, thy sons cherish the Pandavas, and the Pandavas also cherish thy sons. O king, let the Kurus and the Pandavas, both having same friends and same foes, live together in happiness and prosperity. Thou art, today, O king, the refuge of the sons of Kuru. Indeed, the race of Kuru, O Ajamida, is dependent on thee.

In plain words: Vidura says wealth built on both strength and gentleness passes safely to children and grandchildren. He begs the king to let his sons and the Pandavas (his nephews) care for each other and live together happily with the same friends and enemies. He reminds the king that the whole Kuru family depends on him.
