{But that the world may know} (all' hina gn(9369) ho kosmos).
Purpose clause with hina and the second aorist active
subjunctive of gin(9373)k(935c). Elliptical construction (cf.  9:3  13:18  15:25 ). "But I surrendered myself to death," etc., before
hina. {Arise, let us go hence} (egeiresthe, ag(936d)en
enteuthen). Imperative present middle of egeir(935c) and the
volitive (hortatory) subjunctive ag(936d)en (the word used in
 11:7,16 ) of going to meet death. Apparently the group arose and
walked out into the night and the rest of the talk (chs. 15 and
16) and prayer (ch. 17) was in the shadows on the way to
Gethsemane.
