John 8:51

Therefore the emphasis in the next verse, precisely as in John 8:24 of chap. 5, is on “ my word”. ἐάν τις … αἰῶνα, “if any one keeps my word, he shall never see death”. For τηρεῖν see John 14:15-23; John 15:10-20; John 17:6; John 17:1 John and Rev. passim; it is exactly equivalent to “keep”. θεωρεῖν θάνατον occurs only here. It is probably stronger than the commoner ἰδεῖν θάνατον (Luke 2:26; Hebrews 11:5), “expressing fixed contemplation and full acquaintance” (Plummer); although in John this fuller meaning is sometimes not apparent.
