After the religious debates of Luke 20 and Jesus silencing all his enemies, Luke seems to imply that Jesus simply looked up from where he taught in the previous chapter (Luke 21:1). However, Mark seems to say Jesus moved to a position near the place in the Temple treasury where Jews deposited their offerings (Mark 12:41), and there he observed what was done. Nevertheless, whatever actually occurred, the fact is that Jesus had to call his disciples to himself (Luke 21:3), and this does indicate Jesus was no longer formally involved in teaching them. So, the debates were over, and Jesus moved on to something else.
