'Empty' in the Bible

They said, “If you send away the ark of the God of Israel, do not send it empty [without a gift]; but be sure to return [it] to Him [together with] a guilt offering. Then you will be healed, and it will be known to you why His hand is not removed from you.”

You must not turn away, for then you would go after futile things which cannot profit or rescue, because they are futile.

Then Jonathan said to David, “Tomorrow is the New Moon [festival], and you will be missed because your seat will be empty.

The king sat on his seat as on previous occasions, on his seat by the wall; then Jonathan stood up, and Abner [his commander] sat down by Saul’s side, but David’s place was empty.

But on the next day, the second day of the new moon, David’s place was empty [again]; and Saul said to Jonathan his son, “Why has the son of Jesse not come to the meal, either yesterday or today?”
