'Ours' in the Bible

And the Philistines, full of fear, said, God has come into their tents. And they said, Trouble is ours! for never before has such a thing been seen.

Trouble is ours! Who will give us salvation from the hands of these great gods? These are the gods who sent all sorts of blows on the Egyptians in the waste land.

And, now, by all the desire of thy soul, O king, to come down, come down, and ours is to shut him up into the hand of the king.'

The men treated us well. When we were in the field, we weren’t harassed and nothing of ours was missing the whole time we were living among them.
