What is the significance of the name 'Bramble Barn', the area in Kena'an where they eulogized Ya'akov?
Rashi #1: Because it took place in a barn (granary) that was surrounded by brambles.
Rashi #2 (citing Sotah 13a): All the kings of Kena'an and princes of Yishmael came to make war. However, when they saw Yosef's crown hanging on his father's coffin, they stopped short, and hung their own crowns around the coffin beside his. The Torah compares the sight of many crowns hanging round Ya'akov's coffin to a granary surrounded by a thorn-fence.
Why did Yosef make an Avel (mourning) for his father there? Aveilus is only after burial!
