6. Greek, "For I am already being offered"; literally, as a libation; appropriate to the shedding of his blood. Every sacrifice began with an initiatory libation on the victim's head (compare Note, see on Php 2:17). A motive to stimulate Timothy to faithfulness—the departure and final blessedness of Paul; it is the end that crowns the work [BENGEL]. As the time of his departure was indicated to Peter, so to Paul (2Pe 1:14).
