'Ours' in the Bible

And the herdmen of Gerar did strive with Isaac's herdmen, saying, The water is ours: and he called the name of the well Esek; because they strove with him.

For all the riches which God hath taken from our father, that is ours, and our children's: now then, whatsoever God hath said unto thee, do.

Shall not their cattle and their substance and every beast of theirs be ours? only let us consent unto them, and they will dwell with us.
