Charles Ellicott Commentary Luke 21:9

"And when ye shall hear of wars and tumults, be not terrified: for these things must needs come to pass first; but the end is not immediately." — Luke 21:9 (ASV)

Commotions.—The word does not occur in the other Gospels, but is used by St. Paul in 1 Corinthians 14:33 (“confusion”), 2 Corinthians 6:5; 2 Corinthians 12:20 (“tumults”). Its exact meaning is unsettlement, disorder.

Be not terrified.—The word is used by St. Luke only, here and in Luke 24:37, in the New Testament.

By and by.—Better, as elsewhere, immediately.
