Jerome : (Verse 23.) Your leaders were disobedient, partners of thieves. Aquila, departing from the disobedient, interpreted for Symmachus, who turned aside. But the leaders called the scribes and the Pharisees, who departed from the Lord, indeed, abandoning the path of truth, they walked in a crooked way, and became accomplices of the traitor and the thieves of Judah. Indeed, we must be careful not to be called thieves ourselves, but rather partners of thieves, by accepting gifts from the people of the world who accumulate riches through the tears of the poor and through robberies. And it is said to us, You saw a thief, and you ran with him, and with adulterers you set your portion (Ps. 49:18). Everyone loves gifts, they pursue rewards. Even those who love gifts are counted among the vices. It is not said about those who receive: for this often happens out of necessity; but about those who do not consider friends unless they have received gifts from them: they do not consider their friends' faces, but their hands; and they judge as holy those whose purse they empty; about whom Ecclesiastes also speaks: Whoever loves money will not be satisfied with money (Eccles. V, 9). Such are the following retaliations, that they praise those from whom they have received something, or certainly they give nothing unless they think they will receive it from whom. As for retaliations, Symmachus interpreted them as vicissitudes or vengeance, so that those who repay evil for evil and tooth for tooth, eye for eye (Exod. XXI) are also at fault; and they do not imitate that of David: If I have repaid those who repay me with evil (Psal. VII, 5); and of Jeremiah saying of the just man: He will give his cheek to the striker, he will be filled with reproaches (Lam. III, 30): to fulfill the Evangelical man, about whom it is said: If someone strikes you on the cheek, offer him the other cheek also (Matth. V, 39). — Commentary on Isaiah
