Luke 22:45-46

Return of Jesus to His disciples. ἀπὸ τῆς προσευχῆς : rising up from the prayer, seems to continue the narrative from Luke 22:42. ἀπὸ τῆς λύπης, asleep from grief, apologetic; Hebraistic construction, therefore not added by Lk., but got from a Jewish-Christian document, says J. Weiss (in Meyer). Doubtless Lk.'s, added out of delicate feeling for the disciples, and with truth to nature, for grief does induce sleep (“moestitia somnum affert,” Wolf).
