'Sending' in the Bible

'Every one who is sending away his wife, and marrying another, doth commit adultery; and every one who is marrying her sent away from a husband doth commit adultery.

They said then to him, 'Who art thou, that we may give an answer to those sending us? what dost thou say concerning thyself?'

and at the same time also hoping that money shall be given to him by Paul, that he may release him, therefore, also sending for him the oftener, he was conversing with him;

for it doth seem to me irrational, sending a prisoner, not also to signify the charges against him.'
