Muffled
Jesus in me
The most common explanation is that the fig tree symbolized the House of Judah (which had put an Herodian foreigner as its king), and Jesus was cursing Judah for doing so. And of course he was cursing the Pharisees for their accommodation of foreign rulers and Hedllenic apostasy.
I believe this is a bit of a stretch. I wouldn't categorically rule it out but there aren't any clues in the text to support it.
Thereis the parable of the fig tree in Luke 13:6-9 which appears to relate to repentance. I suppose cursing the fig tree could be an object lesson related to the parable. As such it would be a very graphic warning for those who were unrepentant.
