Mk 9:29a ... And he said to them, ...

Verse 29 has three phrases with a total of 16 words. The first phrase has these 3 narrator words, ... kai eipen autois (And he said to them, ...).

The 3 narrator words are top down tangent to three disciples on each side of a Prayer and Fast triangle inside the house. Jesus is standing in the Holy Spirit triangle and an "Unclean Spirit" sits at the bottom of the graph. The three disciples are waiting to hear from Jesus why they could not cast the Unclean Spirit out. Their collective images will not be needed in the diagrams his next words generate.
