'Dew of Heaven' in the Bible

But the stump of its roots leave in the earth, {along with} a band of iron and bronze; [leave it] in the grass of the field. And in the dew of heaven let it be watered, and with the animals let his lot [be] in [the] grass of the earth.

And [inasmuch] that the king saw [the] watcher, a holy [one] coming down from heaven and he said, "Cut down the tree and destroy it, but the stump of its root in the earth leave with a band of iron and bronze in the grass of the field, and let it be watered with the dew of heaven and [let] his lot [be] with [the] animals of the field {until seven times have passed over him}."

you will be driven away {from human society} and {you will dwell} with the animals of the field, and you will be caused to graze grass like the oxen {yourself}, and you will be watered with the dew of heaven, and seven [periods of] time will pass over you until that you have acknowledged that the Most High [is] sovereign over the kingdom of humankind, and {to whom he wills} he gives it.

{Immediately} the word was fulfilled {concerning} Nebuchadnezzar, and he was expelled from {human society} and he ate grass like oxen, and his body was bathed with the dew of heaven until his hair [was] like [the hair of] an eagle and his nails grew like bird's [claws].

And he was driven away {from human society} and his mind was made like the animals and his dwelling [was] with the wild asses; [and] {he was given} grass like oxen to eat, and with the dew of heaven his body was bathed, until he acknowledged that the Most High God [is] sovereign over the kingdom of humankind, and {whoever} he wants he sets over it.
