Now therefore I beseech you as my friend and true vassal, that you go to Zamora to my sister Dona Urraca, and say unto her again, that I beseech her to give me the town either for a price, or in exchange, and I will give to her Medina de Rio-seco, with the whole Infantazgo, from Villalpando to Valladolid, and Tiedra also, which is a good Castle; and I will swear unto her, with twelve knights of my vassals, never to break this covenant between us; but if she refuseth to do this I will take away the town from her by force.
Then said my Cid, The King your brother sends to greet you, and beseeches you to give him this town of Zamora, either for a price or in exchange; and he Will give to you Medina de Rio-seco, with the whole Infantazgo, from Villalpando to Valladolid, and the good castle of Tiedra, and he will swear unto you, with twelve knights his vassals, never to do you hurt or harm; but if you will not give him the town, he will take it against your Will.
