'Dew' in the Bible

"Cut down the tree and cut off its branches. Strip off its foliage and scatter its fruit. Let the animals get out from under it, and let the birds leave its branches. Nevertheless, leave the stump and its roots in the ground, but bind it with iron and bronze in the field grass. Let him be drenched with dew from the sky, and let him graze with the animals in the grass of the earth.

"Your majesty saw a holy observer descending from heaven and saying, "Cut down the tree and destroy it, but leave the stump in the ground, along with its roots, bound with iron and bronze in the field grass. Let him be soaked with the dew of the sky and live with the wild animals of the field until seven seasons pass over him.'

You'll be driven from people, and you'll live among wild animals of the field. You'll eat grass like cattle and be soaked with the dew of the sky while seven years pass you by until you realize that the Most High is sovereign over human kingdoms and grants them to whomever he desires.

The decree was fulfilled against Nebuchadnezzar immediately. He was driven away from people to eat grass like cattle, and his body was drenched with dew from the sky, until his hair grew like eagles' feathers and his nails like birds' claws.

He was driven away from human society and given the mind of an animal. He lived with wild donkeys, ate grass like cattle, and his body was soaked with dew from the sky until he realized that the Most High God is sovereign over human kingdoms and places over them whomever he desires.
