'Empty' in the Bible

They said, "If you [are] sending the ark of the God of Israel away, you must not send it away empty, but by all means return it with a guilt offering. Then you will be healed and it will become known to you why his hand [is] not turned aside from you."

Then Jonathan said to him, "Tomorrow [is] the new moon, and you will be missed, for your seat will stay empty.

The king sat at his seat {as before}, the seat by the wall, and Jonathan got up, and Abner sat beside Saul, but David's place was empty.

{And then} on the next day, the second day of the new moon, that David's place was empty. So Saul asked Jonathan his son, "Why did the son of Jesse not come either yesterday or today to the feast?"
