At the climax of a powerful parable, a bleak political and social reality unfolds. The most capable and worthy individuals withdraw from leadership, leaving the desperate masses to crown the most inferior and destructive candidate available. The search for a king only turns to the lowest option after all other avenues have failed. The respected members of society—the wise, the wealthy, and the established leaders—have already refused the crown. Their refusal stems from a deep understanding that true leadership is not about power and honor. Instead, it requires slavery, toil, and constant instability. A truly worthy leader does not chase authority, knowing that accepting it means sacrificing personal virtues, wealth, and joy [אברבנאל].
Left without guidance, the simple, everyday people—represented in the story by barren trees—are forced to look elsewhere [מלבי"ם]. Out of sheer desperation, they turn to a thorny bush. The primary approach among commentators is that this bush is a lowly, unimportant thistle that produces no fruit [רש"י, מצודת ציון, רלב"ג, ביאור שטיינזלץ]. This choice perfectly symbolizes Abimelech, highlighting his absolute lack of qualifications. Just like the dry thistle, he possesses no noble lineage, honor, wealth, or any ability to bring benefit to those around him [רלב"ג, אברבנאל].
The tragedy deepens because this new leader is not merely useless; he is actively harmful. Any contact with the thorny bush brings pain and sorrow. Its only distinguishing feature among the barren trees is a coat of sharp thorns that keeps others at a distance. This physical trait points directly to Abimelech's cruel and murderous personality, showing that his only real advantage is his capacity for violence [מלבי"ם, אברבנאל]. Ultimately, the story exposes the sheer absurdity of giving power to someone completely empty of positive traits, whose entire existence is defined by damage and destruction.
