'Empty' in the Bible

They said, "If you send the Ark of the God of Israel back, don't send it empty, but rather be sure to send back to him a guilt offering. Then you will be healed and will know why his oppression has not been removed from you."

Jonathan told him, "Tomorrow is the New Moon, and you will be missed because your seat is empty.

The king sat down at his place as before, in the seat by the wall. Jonathan stood while Abner sat next to Saul, but David's place was empty.

But the next day, on the second day of the New Moon, David's place was empty, and so Saul told his son Jonathan, "Why didn't Jesse's son come to the festival, either yesterday or today?"
