And he caused [it] to be proclaimed and published through Nineveh,.... By a herald or heralds, sent into the several parts of the city:by the decree of the king and his nobles; with whom he consulted, and whose advice he took; and who were equally concerned at this news, and very probably were present when word was brought to the king concerning it:saying, let neither man nor beast, herd nor flock, taste anything; a very strict and general fast this: abstinence from all food was enjoined; not only men of every rank and age, but the cattle likewise, horses and camels, they used either for their pleasure or business; their oxen, cows, and calves, of their herd; their sheep, goats, lambs, and kids, of their flocks:let them not feed, nor drink water; no food were to be put into their mangers or folds: nor were they to be suffered to graze in their pastures, or to be allowed the least quantity of food or drink; this was ordered, to make the mourning the greater; thus Virgil describes the mourning for the death of Caesar by the oxen not coming to the rivers to drink, nor touching the grass of the field; and to afflict their minds the more, and for their greater mortification, since these creatures were for their use and pleasure, Fasting was used by the Heathens; as well as the Jews, in some cases; particularly the Egyptians, as Herodotus observes, from whom the Assyrians might take it.
