'Sending' 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."

So David said to Ahimelech the priest, "The king charged me [with] a matter and said to me, 'No one must know anything about this matter [on] which I am sending you, [with] which I have charged you and the servants.'" So {I have arranged to meet with my servants at a certain place}.
