Genesis 27:28 “Therefore God give thee of the dew of heaven….”
What causes dew?
When the air is completely full of water vapor it is said to be soaked or saturated. You may be more familiar with steam, fog, or mist, which is water vapor. When you have the atmosphere (air about earth) filled full of vapor, you have droplets of water so small that they float in the atmosphere.
So when you have the water vapor or moisture in the air it gathers together, it forms into a liquid on something that you would see as on a blade of grass. Dew is formed when warm saturated air cools.
