'Empty' in the Bible

They said, "If you send away the ark of the God of Israel, don't send it empty; but by all means return him a trespass offering: then you shall be healed, and it shall be known to you why his hand is not removed from you."

Then Jonathan said to him, "Tomorrow is the new moon: and you will be missed, because your seat will be empty.

The king sat on his seat, as at other times, even on the seat by the wall; and Jonathan stood up, and Abner sat by Saul's side: but David's place was empty.

It happened on the next day after the new moon, the second day, that David's place was empty. Saul said to Jonathan his son, "Why doesn't the son of Jesse come to eat, neither yesterday, nor today?"
