Private Instruction, Public Summary
The detailed explanations in the Synoptic Gospels almost always happen privately — the crowds get parables, the disciples get keys.
A consistent pattern across Matthew, Mark, and Luke: Jesus teaches crowds in parables and general statements; private instruction to disciples contains the explanations and the harder doctrines. The sower is explained privately (Matthew 13:10, 18); the transfiguration is seen only by three disciples (Matthew 17:1); the Olivet Discourse is given on the mountain to four disciples privately (Mark 13:3); Gethsemane is witnessed by three (Matthew 26:37). The feeding discourses in John are public; the foot-washing is private. The private/public asymmetry of content is consistent enough to be a structural feature of all four gospels, not an accident of narrative.
Red Letter Sources
Matthew 13:11
He answered and said unto them, Because it is given unto you to know the mysteries of the kingdom of heaven, but to them it is not given.
Evidence Notes
Matthew 13:36 explicitly notes that Jesus 'sent the multitude away, and went into the house' before explaining the wheat and tares.
Correction Note
Source verses corrected 2026-06-20: Mark 13:3 reclassified to context_verses — narrator setup ('And as he sat upon the mount of Olives...Peter and James and John and Andrew asked him privately'), not red-letter speech. Matthew 17:1 was moved to context_verses 2026-06-19. Red-letter evidence stands on Matthew 13:10–11 (Jesus explaining why he speaks in parables to crowds and keys to disciples). Core claim survives.
