Matthew 24:4 - Ellicott's Commentary On The Whole Bible

Jesus answered and said unto them... — The great discourse which follows is given with substantial agreement by St. Mark and St. Luke, the variations being such as were naturally incident to reports made from memory, and probably after an interval of many years. In all probability, the written record came, in the first instance, from the lips of St. Peter, and it will accordingly be instructive to compare its eschatology, or “teaching as to the last things,” with that which we find in his discourses and epistles. St. Paul’s reference to “the day of the Lord “coming” as a thief in the night” (1 Thessalonians 5:2) suggests the inference that its substance had become known at a comparatively early date; but it was probably not published, i.e., not thrown as a document into circulation, among Christian Jews, till the time was near when its warnings would be needed; and this may, in part, account for the variations with which it then appeared.
