Mark 10:2-12 is a controversy on the question of divorce introduced by a geographical note in verse 1, Jesus' nearness to Jerusalem. The location
given by Mark is "in the regions of Judea beyond the Jordan". While there, the crowds come to Jesus who then begins to teach; among those present were the Pharisees.
This section from Mark can be easily divided into two parts: (a) the controversy on divorce (vv. 2-9), and (b) the instruction to the disciples (vv. 10-12). It is to be noted that v. 10 begins a location, "inside the house once more", which is problematic: which house is this? Is this the same house in 9:33? If this is the case then the reader will have to imagine a lapse of time between the controversy with the Pharisees and the private instructions to the disciples. Is this a different house, this time located in the regions of Judea beyond the Jordan? Or is this a case where two independent stories were brought together in Mark? J. Gnilka tells us that Mark already found these stories placed side by side with one another, although they were once independent, as can be seen from Matthew 19:1-9 which is followed by an instruction to the disciples on an altogether different matter (see Matthew 19:10-12). In any case, we have here in Mark a disputed question which later on gives Jesus an opportunity for further instructing his disciples.
