Ezra 7:22 - Joseph Benson’s Commentary on the Old and New Testaments

Salt, without prescribing how much He limits all the other expenses, except salt, which was of low price, and of very common and necessary use in all their sacrifices; and therefore, since he would not have any sacrifice hindered, he did not prescribe any measure of it, but permitted them to take as much as they found necessary. The sum here ordered, in silver, amounts to thirty-five thousand three hundred pounds sterling; the wheat to eight hundred bushels; the wine to twelve or thirteen hogsheads; and the oil to the same quantity, which shows the princely liberality of Artaxerxes.
