Will ye plead for Baal? - The words are very emphatic "Will ye plead in earnest תריבן for Baal? Will ye תושיען really save him? If he be God, אלהים Elohim, let him contend for himself, seeing his altar is thrown down." The paragogic letters in the words plead and save greatly increase the sense. Joash could not slay his son; but he was satisfied he had insulted Baal: if Baal were the true God, he would avenge his own injured honor. This was a sentiment among the heathens. Thus Tacitus, lib. i., c. 73, A.U.C. 768, mentioning the letter of Tiberius to the consuls in behalf of Cassius and Rubrius, two Roman knights, one of whom was accused of having sold a statue of Augustus in the auction of his gardens; and the other, of having sworn falsely by the name of Augustus, who had been deified by the senate; among other things makes him say: Non ideo decretum patri suo coelum, ut in perniciem civium is honor verteretur. Nec contra religiones fieri quod effigies ejus, utalia nu minum simulachra, venditionibus hortorum et domuum accedant. Jusjurandum perinde aestimandum quam si Jovem fefellisset: deorum injuriae diis curae - "That Divine honors were not decreed to his father (Augustus) to lay snares for the citizens; and if his statue, in common with the images of the gods in general, was put up to sale with the houses and gardens, it could not be considered an injury to religion. That any false oath must be considered as an attempt to deceive Jupiter himself; but the gods themselves must take cognizance of the injuries done unto them." Livy has a similar sentiment, Hist. lib. x., c. 6, where, speaking of some attempts made to increase the number of the augurs out of the commons, with which the senators were displeased, he says: Simulabant ad deos id magis, quam ad se pertinere; ipsos visuros, ne sacra sua polluantur. - "They pretended that these things belonged more to the gods than themselves; and that they would take care that their sacred rites were not polluted."
From the boldness of Joash in defending his son, it is likely that the majority of the Abi-ezrites sided with him against “the men of the city,” and already felt drawn toward Gideon as their national and religious leader Judges 6:34. Joash appears as the chief magistrate of Ophrah.
Will ye plead ? will ye save? - The emphasis is upon ye, as much as to say, What business is it of yours?
