Mark 13:5
Jesus said to them: watch out that no one deceives you — the discourse opens with a warning about deception, not a description of the end. The first danger is not the events themselves but the false interpretation of the events. Watch out is the repeated command throughout the discourse (verses 5, 9, 23, 33) — the primary ethical demand of the discourse is vigilant, clear-eyed discernment rather than passive waiting.
