"You are his daughters."
Translation:Vous êtes ses filles.
It may help to imagine this scenario:
Fool: "Hello Goneril, Regan and Cordelia"
Regan: "What do you want, Fool?"
Fool: "To ask you to help your King"
Goneril: "We will not"
Fool: "But, you are his daughters!"
Easier to use as a phrase but it can be a sentence on its own:
"The women of the world are the children of God. You are his daughters. Go forth and multiply to honour your God."
