'Piece' in the Bible

Thus says the Lord,“Just as the shepherd snatches from the mouth of the lion a couple of legs or a piece of the [sheep’s] ear [to prove to the owner that he has not stolen the animal],So will the [remaining] children of Israel living in Samaria be snatched awayWith the corner of a bed and [part of] the damask covering of a couch.

“Furthermore, I withheld the rain from youWhen there were still three months until the harvest.Then I would send rain on one city,And on another city I would not send rain;One piece of ground was rained on,While the part not rained on would dry up.
