'Ours' in the Bible

“Listen to us, my lord; you are a prince of God [a mighty prince] among us; bury your dead in the choicest of our graves; none of us will refuse you his grave or hinder you from burying your dead [wife].”

the herdsmen of Gerar quarreled with Isaac’s herdsmen, saying, “The water is ours!” So Isaac named the well Esek (quarreling), because they quarreled with him.

Surely all the riches which God has taken from our father are ours and our children’s. Now then, whatever God has told you to do, do it.”

Will not their cattle and their possessions and all their animals be ours [if we do this]? Let us consent [to do as they ask], and they will live here with us.”
