Bible Notes Online - Judges 9 - ESV
Commentary

v1-3: Abimelech's conspiracy; he used clever words to win over the people of Shechem. This was the family of Gideon's concubine (8.31, and v18). It may have been that Abimelech felt despised (as with Jephtha in 11.1-2). He certainly became proud and deceitful, desiring power and authority. Later, he suggested that he be made king; even Saul, and certainly David, did not do that. He is not actually named as a Judge of Israel.

v4: Abimelech used money from idolatry to pay for "reckless adventurers"; such are not the characteristics of a godly man.

v5: He killed his family, the sons of Gideon, to get his own way, and to ensure his leadership was uncontested. His 'promotion' was linked to the 'demotion' of others. Again, a godly man will not do this.

v6: As a result, the people of Shechem made him king.

v7: Jotham's prophecy; announced from Mount Gerizim, the place of blessing (Deut 27.12).

v8-13: Describing Gideon (8.22-23) who had refused to reign over the people. He knew his calling from God, and he would not take the place of God in the people's minds.

The three trees, the olive tree, the fig-tree, and the vine; all providing a godly example; of worship, of holiness, and of joy. These trees are all pictures of God in the Old Testament. They did not seek supremacy, but were willing to serve God and man. This is what Israel should have been; and what Jesus Christ was, for He is the true vine in John 15,

v14-15: Abimelech was the thorn-bush (or bramble); no desire for fruitfulness to bless others, only selfishness and pride. The Hebrew word suggests 'one who pierces'.

v16-19:   Jotham challenged their motives in making Abimelech king.

v20: The prophecy was that, if the people's motives were not pure, then the unity between Abimelech and Shechem (v3) would be destroyed; this was fulfilled; v23.

v21: Jotham was afraid, like Jether in 8.20.

v23-25: Three years later, the prophecy began to be fulfilled, as Shechem turned against Abimelech. God was bringing upon Abimelech the judgment due him for killing Gideon's sons.

The ill-will between Shechem, led by Gaal, and Abimelech is described in v26-39. Gaal claimed allegiance to Hamor and Shechem (see Gen 34), and stirred up an old animosity between the Hivites and the Israelites. Zebul, the governor of the city, was Abimelech's ally (v28, 30, 38).

As far as the people of Shechem were concerned, they wanted a leader, a hero. If not Abimelech, then Gaal. Neither were worshippers of the true God. We see that, without submission to Christ, there comes personal ambition and rivalry.

v39-45: Having driven Gaal out of Shechem, Abimelech destroyed the city.

v46-49: The remaining people of Shechem sought refuge in the temple of Berith. Abimelech led by example, by bringing branches, so that the temple was burned down, and the people killed.

v50-57: The attack on Thebez was Abimelech's downfall. Although there was ingenuity on the part of the citizens there, the power was God's as He fulfilled His word, and exercised judgment upon Abimelech. Shechem also paid for its treachery against Gideon.The writer is clear that Jotham’s prophecy was fulfilled in these incidents.
