'Ours' in the Bible

But the shepherds of Gerar strove with Isaac's shepherds, saying, The water is ours. And he called the name of the well Esek, because they had quarrelled with him.

For all the wealth that God has taken from our father is ours and our children's; and now whatever God has said to thee do.

Their cattle, and their possessions, and every beast of theirs, shall they not be ours? only let us consent to them, and they will dwell with us.
