[235] Now when, on a certain time, there was a public festival at Shechem, and all the multitude was there gathered together, Jotham his brother, whose escape we before related, went up to Mount Gerizzim, which hangs over the city Shechem, and cried out so as to be heard by the multitude, who were attentive to him. He desired they would consider what he was going to say to them: so when silence was made, he said, That when the trees had a human voice, and there was an assembly of them gathered together, they desired that the fig-tree would rule over them; but when that tree refused so to do, because it was contented to enjoy that honor which belonged peculiarly to the fruit it bare, and not that which should be derived to it from abroad, the trees did not leave off their intentions to have a ruler, so they thought proper to make the offer of that honor to the vine; but when the vine was chosen, it made use of the same words which the fig-tree had used before, and excused itself from accepting the government: and when the olive-tree had done the same, the brier, whom the trees had desired to take the kingdom, (it is a sort of wood good for firing,) it promised to take the government, and to be zealous in the exercise of it; but that then they must sit down under its shadow, and if they should plot against it to destroy it, the principle of fire that was in it should destroy them. He told them, that what he had said was no laughing matter; for that when they had experienced many blessings from Gideon, they overlooked Abimelech, when he overruled all, and had joined with him in slaying his brethren; and that he was no better than a fire himself. So when he had said this, he went away, and lived privately in the mountains for three years, out of fear of Abimelech.
