to send: to dispatch a person, messenger, or thing toward a destination or purpose
The basic act of causing someone or something to go from the sender to a recipient or destination. The sender initiates the movement and stands behind what or whom is sent, but the sender does not necessarily accompany the one sent. The word covers the full range: a king sending soldiers, friends sending greetings, a church sending a delegate, angels sent on divine missions.
In John's Gospel, pempo carries a distinctive theological weight. Jesus speaks repeatedly of "the Father who sent me," a fixed phrase that appears more than a dozen times. The repetition is deliberate: Jesus traces every word he speaks, every work he does, and his very authority back to the Father who dispatched him. Being sent in this sense means acting under the sender's mandate and representing the sender's will completely. John 20:21 draws the line forward: "As the Father has sent me, I also send you."
Paul uses the word practically and affectionately. He sends Timothy to Corinth, Epaphroditus back to Philippi, Tychicus to Ephesus and Colossae, all to serve as his representatives and to strengthen the communities he cannot visit in person. In Revelation, the word governs divine commands ("send your sickle") and the circulation of the book itself ("send it to the seven churches").
