Rashi on the Former Prophets

I have given to the son of your master. The king is permitted to transfer an estate as it is said (Shmuel I, 8:14) Within the jurisdiction of the monarchy is [the power] to take their fields and their vineyards and to give it to his servants.

So will your servant do. Mephivoshes will eat at my table. Tsivoh said, "So will your servant do." And Dovid responded, "Mephivoshes will eat at my table."

Those who dwelled in the house of Tsivoh. His children and his slaves.
